myMeest
Ordering from a shop abroad is not a quest anymore with a convenient myMeest app. This solution works as a mediator between buyers and foreign sellers to make international online shopping more accessible.
The main challenge of the myMeest app was organizing loads of data about shipments into a transparent and standardized system.
We developed a system of symbols, introduced a set of filters, and focused on simple colors to address it. Of course, this would be no use without an elaborate user journey map listing a complete action logic cycle.
With myMeest, users can create and manage shipments, choose warehouses in numerous locations around the globe, and make payments directly in the app. No more parcels lost on the way — buyers can track exactly where their order is and will receive instant updates from the stores and warehouses.
Our final product is a handy and stylish mobile app that gives users complete control over their packagers in just a few clicks. In myMeest, users are intuitively guided throughout their journey, from placing an order to picking up the parcel in a destination country.

Burn app
Burn is an all-in-one fitness app that provides users with everything they need for at-home workouts and a healthy lifestyle.
Our team’s first task was to make sure that all the materials in the app could be downloaded and were suitable for other platforms like Burn’s website and social media. To do so, we developed a unified design system for all the materials across the channels.
One more peculiarity of Burn is that the client contacted us with a website redesign request along with a mobile app design that needed to be made from scratch. Thus, we began the process by preparing unique UI/UX designs for a website and mobile app.
As a result, Perpetio presented web and mobile solutions unified by recognizable UI. The new platforms contain all the users’ favorite content as well as new useful features, like offline videos.
Burn includes loads of fitness content, from downloadable video training sessions to meal plans with recipes. Additionally, we integrated a convenient calendar with a workout schedule, so the users would never skip the legs day again.

MealShare
MealShare is a social network app for exchanging healthy recipes and getting community support.
We didn’t want MealShare to be just one more list of recipes; it should be a platform uniting like-minded people so they can exchange the content in a safe and non-judgmental environment.
MealShare is a convenient cookbook app that contains recipes shared by users. The flow is simple and fun: post a picture of your dish along with a recipe, choose tags for it, such as vegan or gluten-free, and get reviews from other community members. Like this, it’s easy to find a dish for a healthy dinner and get valuable tips from the comment sections.
Additionally, each user can rate the dish based on how healthy it is. If there are any doubts about ingredients or preparation methods, an affordable consultation from a professional dietician is included.
With simple navigation and refreshing UI, MealShare is there for users to find joy in cooking healthy.

SingSnapp
SingSnapp is the world’s largest karaoke streaming service. Perpetio undertook the task of creating a mobile version of the platform.
The main challenge of the SingSnapp app was integrating a professional audio enhancement technology for recording and playing the users’ covers. At the same time, we needed the interface to be user-friendly and extremely easy to grasp.
The final SingSnapp app features an extensive library comprised of tens of thousands of songs. Users can create playlists to organize those and always be ready for a karaoke session.
Community is an essential aspect of SingSnapp. Users can make duets, share their covers, comment, send direct messages, and participate in various contests and challenges.
The Perpetio’s team did our best to combine cutting-edge audio technologies with social media mechanics to create a karaoke app like never seen before.

Shrink
Leading a healthy and eco-friendly lifestyle is easier than ever with the Shrink app. In Shrink, users get discounts, cashback, and rewards for choosing to support eco-conscious and local producers.
Our task was to create an app that works as a meeting point between brands and consumers.
In the Shrink app, users can get quality products for a better price, get acquainted with new producers, and obtain items that might be otherwise hard to find. With a built-in wallet, there is no trouble buying items at a reasonable price directly in the app and using rewards for purchases with a built-in wallet.
At the same time, brands get a pool of potential customers interested in healthy products and sell products that expire soon with a discount. Retailers can also get in touch with customers before, during, and after purchasing. Win-win.
As for the UI, we went for a clean and minimalistic design to focus users’ attention on the products. To make navigation more accessible, we introduced a set of logos in the menu bar. Thus, we got an easy-to-use free app that brings value to customers and retailers.

Selfit
Selfit is a fitness app for people who don’t have time to pay regular visits to the gym or simply choose to exercise at home. With a bright and minimalistic UI design, Selfit offers a set of workouts with step-by-step guidance to allow users to engage at home with no extra equipment.
After doing the user persona research, we drafted two main goals Selfit’s potential users were looking for: staying motivated to keep exercising and having access to ready-made workout routines.
Selfit combines video workout routines and a set of tools for tracking progress and keeping the motivation up. These include a workout calendar, reminders, a system of encouragement messages, as well as reporting about finished workouts and total time spent exercising.
We created a simple yet effective app that is a one-stop shop for everyone looking for guided workouts they can engage in from home. With detailed video instructions, many activities for all levels and preferences, tracking, and motivation tools, there is no chance for users to miss their weekly workout session.

Residio
Residio is an app for finding all kinds of real estate, from renting an apartment for a short term to purchasing a house.
We all know the struggle of finding a perfect house for a reasonable price. Residio is to be the tool that makes the search way more effortless.
Residio offers a system of convenient filters to assist users with finding exactly what they need. Users simply need to log in, choose property type, price range, and other parameters, and voilà — dozens of homes are waiting for them.
One exciting feature of the Residio app is a tag system for property images. By clicking on a photo, users can see the descriptions of all the furniture and other items in the room. These little tips are there to help users make more informed decisions.
Not to overwhelm users and put the real estate content in the center, we went for a minimalistic UI. A set of symbols organizes the information about the house and its amenities. As a result, we have a simple yet stylish app that helps users find a perfect home in a few taps.

Treadly
Connect with friends and enjoy group workouts on the treadmill!
Treadly is a social network that connects people who use a smart treadmill. The app lets users create a variety of challenges, form group chats, call friends and plan workouts together - with everything inside one convenient application! All you need to do is get your personal Treadly device, install the app, and you’re ready to go!

Gravitus
Gravitus is an app for weight lifters that tracks workouts easily with a user-friendly design.
One of the main challenges was the UI - the design needed to maximize lifting and minimize tapping.
Whether users are in the same city or across the country, they can add friends as lifting buddies to help motivate one another. The app also plans workouts ahead of time using a workout template feature, sets up unique training maxes and automatically computes weight goals based on a training max percentages. Another important feature is the app’s ability to monitor users’ progress with beautiful, interactive charts. New exercise videos and tips are included, as well as a leaderboard that allows users to see how they measure up against friends and the Gravitus community – how challenging!

Mealshare
MealShare app mission is to impact health and happiness through healthy eating.
Mealshare app helps listen to your body, create a strong community that's safe, non-judgmental and supportive, and when you really have a question about food or whether something is healthy, you can easily and affordably connect with a real Pro (all registered dietitians).

HipWig
Discover Advisors are incorporated into the app – called HipWig – offering dating tips, relationship advice, help finding love and so much more. People are using this platform to improve their relationships, get pointers on how to date, and simply increase how often they smile!
HipWig is more than a dating app. The app offers helpful tips from a large community of advisors while building valuable relationships every day. Over 25 million people have signed up for this platform to strengthen their relationships, get help with dating, and smile more often.

Flutter-Based App Development for Hearing Health Company
"They integrated with our tools and adapted very easily to them."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
I am head of product development at eargym, your hearing health companion.
For what projects/services did your company hire Perpetio, and what were your goals?
We needed a plugin cost effective Flutter development team to deliver our designs and release regular product updates.
How did you select this vendor and what were the deciding factors?
We shortlisted 10 companies and got quotes from about 6, Perpetio were the most competitive and flexible cost wise.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
Flutter app development, publishing to iOS and Andoid and Play / App stores, QA testing, project management and scoping. The project deliverables are pretty straight-forward UI implementation which is being done to a good standard but there are some more technical challenges in the hearing test and Unity games integration.
How many resources from the vendor's team worked with you, and what were their positions?
2 developers, Mid and jnr, 1 PM, 1 QA 1 account manager and some support from Snr devs and CTO in critical phases.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The project started along side the war with Russia and the team have been 110% dedicated to delivering which has been incredibly impressive. They feel like part of the team, quality of the work is decent and dedication and work ethic impressive.
Describe their project management style, including communication tools and timeliness.
Having a dedicated project manager has been a great help, they integrated with our tools and adapted very easily to them and have been involved in suggesting improvements to workflow which is good.
What did you find most impressive or unique about this company?
Work ethic and valueing being part of the team working on something they are proud of.
Are there any areas for improvement or something they could have done differently?
We hit a few technical challenges along the way which could probably have been resolved more quickly with some earlier senior experience intervention.

iOS Scanner App Design for App Dev Company
"Their professionalism, friendliness and warm personality stood out - they are the kind of people I like to work with."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
Our company is a startup developing business and productivity apps for iOS devices. My position is the founder.
For what projects/services did your company hire Perpetio?
We used Perpetio for user interface design in Figma and some user interaction design.
What were your goals for this project?
The goal was to have a competent UI designer create compelling UI designs that our iOS developer could use to implement our app.
How did you select this vendor?
We used UpWork to submit the project. I selected this vendor based on their great rate and professionalism, I knew right from the start they were a team I could work. It was great to get to know them after unsuccessfully interviewing 3 other designers who appeared to have good profiles but did not show interest or show up on time for the interviews.
Describe the project in detail.
The project involved designing UI wireframes and screens for all of the app screens. The requirements were driven by myself and it was required that the designer attend daily standup meetings. The project consists of many app screens and simplified app flows to provide the best user experience best, whilst hiding the complexity away from the user.
What was the team composition?
We were assigned a project manager, and a talented designer who I worked with on a daily basis. I spoke with the designer daily in our team standup.
Can you share any outcomes from the project that demonstrate progress or success?
We are still implementing many of the screens, but most have been implemented. Already we have seen a dramatic improvement in how our app looks and behaves. We have had external feedback which has been extremely positive. Without these designs our app would have looked unprofessional and been lost in a sea of technical features with no user friendly interface.
How effective was the workflow between your team and theirs?
Our Workflow was great, because we used Figma. I was able to review the work on a daily basis in an agile fashion and provide direct feedback. Although the designer was given some creative freedom I was directly involved in making some decisions since I am overall responsible for the product.
What did you find most impressive about this company?
Their professionalism, friendliness and warm personality stood out - they are the kind of people I like to work with, not only did they show up to the interview on time, they were always on time for meetings and daily standups. They have a genuine interest in making progress and generating results.
Are there any areas for improvement?
I have only good things to say about them, but my only offer of advice would be take more time to understand the requirements and ask more questions if something is not clear - it's not always about delivering the quickest results. Of course this could be different with every client, since I am a hands-on client, I expect this, others may prefer to just leave them to get on with the work.

"I’m more than happy with the result, and the app is better than how I thought it would be."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
I’m a self-employed musician and the CEO of my own company. I'm a freelance composer for TV shows and commercials and recently stepped into the business of creating a music app.
For what projects/services did your company hire Perpetio?
I hired Perpetio to help design and build the app from the ground up.
What were your goals for this project?
The goal was to create a brand new, never-before-created music reference app that would aid musicians and teachers through their cellphone. I wanted to better support musicians and teachers who were working with students or creating new music for instruments.
How did you select this vendor?
I went through a freelancer site and reviewed their previous work and designs against other companies. Perpetio stood out amongst the competition.
Describe the project in detail.
Once I selected Perpetio, we had Skype meetings to discuss our ideas and the processes we would take to get to our end goal. I had to spend a lot of time providing information for the app since it's a reference application. Afterward, we were able to get all of the information together and slowly build the app.
What was the team composition?
I’m not entirely sure what the exact team composition was, but they have a builder, a designer, and a project manager who all worked together to build a work of art!
Can you share any outcomes from the project that demonstrate progress or success?
The app is currently still in beta testing, and edits are being made to make sure that we release something that everyone can’t wait to get their hands on.
How effective was the workflow between your team and theirs?
The workflow was good overall, but also a bit slow at times. It would take a while for us to get back to each other via email, but my schedule is insanely busy as well, so I can’t blame them for that.
What did you find most impressive about this company?
The excellent design, cohesive creation, and understanding of my idea are what truly blew my mind. I commend them for what they’ve delivered. I’m more than happy with the result, and the app is better than how I thought it would be.
Are there any areas for improvement?
Maybe the speed of communication, but other than, that they’ve done everything extremely well!

Shopify Website & Android App for Electronics Company
“Their quality of work is on par with our internal team.”
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m a co-founder and CTO for an IoT company that helps people manage access to their homes.
What challenge were you trying to address with Perpetio?
We had numerous projects and not enough internal resources, so we began looking for a partner who could quickly integrate with our team.
What was the scope of their involvement?
The main project Perpetio worked on was our Shopify website. They developed and designed the whole thing, creating both an informational and e-commerce platform. They also do software and Android development along with app design.
What is the team composition?
They have a project manager, and we also directly interact with the designers and developers.
How did you come to work with Perpetio?
One of our employees had worked with them before and had a good experience, so we hired them.
What is the status of this engagement?
We partnered in September 2018, and the work is ongoing.
What evidence can you share that demonstrates the impact of the engagement?
They’ve saved us lots of money by not having to hire in-house designers and developers. Their quality of work is on par with our internal team.
How did Perpetio perform from a project management standpoint?
The project manager keeps us focused and on track, holding phone calls twice a week to make sure everyone’s on the same page. We also use Trello and email to communicate.
What did you find most impressive about them?
They’re capable engineers with strong experience, so they require minimal oversight.
Are there any areas they could improve?
No, I can't name anything.
Do you have any advice for future clients of theirs?
Get a quote before you start. We didn’t, and the invoice was reasonable, but it would’ve been nice to know the cost at the beginning of our partnership.

App Dev for iOS Fitness Platform
"We've partnered with other development firms in the past, and Perpetio stands out from the rest."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I am the CEO of a small tech startup.
What challenge were you trying to address with Perpetio?
We manage a mobile app that’s available on iPhones, and we needed to strengthen our internal development capabilities. Specifically, we were looking for a vendor to provide a few resources to help us with backend server development.
What was the scope of their involvement?
Perpetio assigned two developers to work with our in-house team on a new feature for our mobile fitness app. We shared our specifications and designs, and they built it out through a series of two-week sprints with daily scrum meetings. The Perpetio team worked with Python and Django technology for the backend, and Swift on the frontend. The new feature allows users to plan individual workouts through the application.
What is the team composition?
We worked with an iOS developer and a server engineer.
How did you come to work with Perpetio?
A friend recommended Perpetio to us, and based on her recommendation, we decided to work with them.
How much have you invested with them?
We spent $100,000.
What is the status of this engagement?
We worked with them on this project from April—December 2018. We plan to work with them again on future projects.
What evidence can you share that demonstrates the impact of the engagement?
I don’t have any metrics that relate to their specific involvement, but I can say that they have great developers, and our existing team loves working with them. I have nothing but positive things to say about them.
How did Perpetio perform from a project management standpoint?
We handled most of the project management responsibilities on our end, and Perpetio worked seamlessly with us. All communication was easy and straightforward, and they were always responsive to our feedback, which set the foundation for a quick turnaround time.
What did you find most impressive about them?
We’ve partnered with other development firms in the past, and Perpetio stands out from the rest. It was a very easy collaboration. They communicated with precision and efficiency, especially when dealing with project setup and billing details.
Are there any areas they could improve?
No, I can't think of any at this time.

We worked with a project manager, a UI/UX designer, and some developers.
Can you share any information that demonstrates the impact that this project has had on your business?
Our new website has led to an improved conversion rate.

Mobile App Dev for Fitness Providers Networking Platform
"They were proactive and independent, which is really nice because I wanted more than just a 'Yes Man.'"
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the founder of a fitness app that connects people to fitness providers. We’re about purchasing fitness packages on demands with no contracts.
What challenge were you trying to address with Perpetio?
We needed to introduce some functionality to our platform earlier than previously planned.
What was the scope of their involvement?
They worked on existing backend code of all four parts of our ecosystem: a mobile app, a web panel for clients and fitness providers, an admin panel on our side that managed all the incoming data, and a website. They changed some of the methodologies we were using and factored some additional algorithms into the pricing. They also helped us adhere to the new GDPR regulations and made some minor to medium bug fixes.
What is the team composition?
We worked with a backend developer, an iOS developer, a project manager, a QA resource, and a UI designer.
How did you come to work with Perpetio?
We reached out to a company that has a network of development agencies and they put us in touch with Perpetio. I had five requirements: flexibility to work on existing code, staying in-line with my budget, having people available to work on the project, keeping to our timescale, and being personable and demonstrating interest and initiative.
How much have you invested with them?
We spent £10,000– £15,000 ($13,005–$19,508 USD)
What is the status of this engagement?
We worked together from February until May 2018.
What evidence can you share that demonstrates the impact of the engagement?
In terms of technical ability, I would score most of the developers at a 10. They knew their stuff. I was slightly disappointed on the QA side of things though. I think that the QA person was a newer employee, so I would rate the QA lower.
How did Perpetio perform from a project management standpoint?
I would give project management an eight. They were strong on the project's overall setup and kept a regular cadence of meetings. They were flexible and adaptable to changing requirements, especially towards the end of the scope. There was a bit of ambiguity with role definition at the overall project manager / relationship manager level, but it didn’t hurt us too much.
They were super responsive and set up a Slack channel so that I could be in constant communication with each of the developers. They would work weekends and off-hours just because they wanted to.
What did you find most impressive about them?
The developers would constantly think of alternative options. They were proactive and independent, which is really nice because I wanted more than just a “Yes Man.” They really owned the role. It’s very rare, especially with people I’ve worked with in the past—and a lot of agencies get really bad press for only doing what you ask. It certainly makes me want to work with them again and recommend them.
Are there any areas they could improve?
I had to do more handholding with QA that I expected, but that might just be the person rather than the nature of the company.
Any advice for potential customers?
You should have a super clear picture of all the deliverables and of the level of priority of each, especially if it’s with inherited code. If you don’t then you’ll waste a lot of time up front deciding what exactly you want. It’s up to the business to know what exactly they want in the development cycle.

Android Development Partner for Startup
“Every single deadline was met. If a project fell behind, they took time out of their weekend to make sure it was done.”
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I run a startup. I also do part-time contracting for my own firm.
What challenge were you trying to address with Perpetio?
There were a lot of people coming to us for multi-platform apps. We were understaffed in the Android department and needed someone to help us.
What was the scope of their involvement?
They’ve worked on three or four projects for us. The iOS app usually gets completed first. I usually do the wireframes with the client and get all the specifications needed for the Android app, then I present Perpetio with that information. I interfaced with one person on a high level to architect the project and pass over the requirements. When the project got started, I interfaced directly with the developer on the project. I had continual contact with three resources from their team. I’m a developer myself, so a lot of our contact was just working alongside them.
How did you come to work with Perpetio?
I had worked with another one of their business contacts on a separate project. He recommended Perpetio for Android development. I asked them for projects they’d done before. After seeing the quality of the first product, I trusted them.
How much have you invested with Perpetio?
We’ve spent over $20,000 with them so far.
What is the status of this engagement?
We started working with them in September 2016, and the work is ongoing. They’re still available to fix bugs and maintenance of the apps. I’ll definitely continue to use them as needed for Android development.
Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?
We use WeWork, which gives a good breakdown on their productivity and what they’re working on at the moment. They’re quite productive. I’ve looked at the code, and it’s good, quality code. I’m a hands-off type of guy. We communicate via Skype, and I give them the idea and they get to work. They do 40 hours per week at the maximum capacity for one developer, but it varies depending on the project requirements.
How did Perpetio perform from a project management standpoint?
I have no complaints. As a project manager myself, I have different philosophies, but that indicates that they’re adaptive to other people’s needs. They exceeded all my expectations. Our relationship is pretty good. There is no problem with time difference or language barrier. If I was in Ukraine on holiday, we have the kind of relationship that we would meet and hang out. We use WeWork for time tracking and Skype to communicate.
What did you find most impressive about Perpetio?
When I came to them, I already had near completed iOS apps and asked for an Android app just like it. The conversation wasn’t really any longer than that. Two weeks later, it was done. When you’re managing so many things, it’s really convenient to have a team that can just do it without a lot of instruction.
Are there any areas Perpetio could improve?
There was one instance where they put a more junior developer on my project. That didn’t work out so great, but they made the problem right so I can’t complain.
The company is impressed by Perpetio's dedication to delivering their mobile app; the team works as part of the firm's internal staff and provides quality work with great work ethics. Their project management style has been good, and their resources adapt well to the client's workflow and processes.
