AR-based app for iOS built with Swift and ARKit Image

AR-based app for iOS built with Swift and ARKit

The client came to us with an idea of writing an AR-based app for his cosmetics stores. Our task was to take self-care to a new level. Using the application, the client should receive maximum information about the products without resorting to the help of consultants. Face recognition and AR tools allow trying a range of products without applying them to the face. The voice assistant helps the user to navigate the products, check their’ availability, and the location in the store.

We’ve created a design and PoC for this application. This product could be easily adapted for any retail business.

Native iOS and Android apps for a fast, comfortable and cost-friendly ride

The owners of a taxi service asked us to develop a new application for their business. The previous version did not meet their requirements in terms of design, code quality, and speed. We started from scratch and developed branding and UI/UX design for this project. 70+ screens turned into 4 apps: one for drivers and one for customers, each one for iOS and Android. The alpha version is already in testing. The first results show

that the app can handle high loads, and its interface is more user-friendly than the previous version.

Feedback summary: 

Based on early testing and interviews, they have concluded that users have responded well to the new UI and will be making the necessary adjustments before it goes live. They maintained excellent communications and had no problem adapting to the client's needs and resolving any issue that comes up.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am the CTO and co-founder of Snapmentor.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack, and what were your goals?

We needed velocity in our delivery to meet our customers needs and to push out a completely new extension to our services. The project ended up in a information architectural change which led to a UI rewrite of our main web application. The goal of the project was to build up a simple design system of components that together would compose the web app pages.

SOLUTION

How did you select Mentalstack and what were the deciding factors?

We did an extensive interview process with a lot of designers on UpWork. What was a deciding factors with Mentalstack was their professionalism and structure in project management.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

The scope of work was to extend Snapmentors main software with a knowledgebase that added a lot of complexity and features for our customers. We relied on a heavily agile work process. We worked in sprints with bi-daily standups to discuss and review design and development. Key deliveries were design wireframes and Pull requests made with react and storybooks. The technologies used was mainly figma for design along with well known web development framework technologies such as react, styled-components, storybook etc.

How many people from the vendor's team worked with you, and what were their positions?

We had one designer, one developer and one project manager.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

For measurable outcomes that is still a bit early. We are making the final changes before our release to customers now a days. What we know is that through user interviews, usability testing and observation we see that in general this meets our customers needs and is scalable for our business.

Describe their project management style, including communication tools and timelines.

We mainly used slack for communication and it was super easy with Mentalstack. They are provisient in english and professional. For task management we used trello. Maria, the manager was very good. She kept structure and was also on top of details regarding the design. I don't know how much they communicated on their side, but they had no problems handling all the details. I think we had a very good communication throughout the project.

What did you find most impressive or unique about this company?

For what I see, the combination of a project manager along with a technical resource was a good combination because the manager handled a lot of the structure which allowed the technical resource to focus on the creativity and difficult things.

Are there any areas for improvement or something they could have done differently?

We had a slight miscommunication in the beginning of development where some design had deviated from how the functionality would work, so we lost perhaps one day of work in the wrong direction. Asking clearifying questions are very important and a short feedback loop equally important. For the design, I understand it is hard, but if I would work with mentalstack the next time, I would like to have a shorter feedback loop from design to implementation than we had. We discovered that we had some gaps where when we started the implementation we found some issues, which is something you normally do, but then we had completed the design contract.

Feedback summary: 

Mentalstack delivered a superior website that satisfied internal stakeholders. By leveraging Figma, the team encouraged feedback and streamlined collaboration. An engaged project manager facilitated an effective partnership. Despite minimal direction, they captured the client’s vision in the design.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the director of technology at Home Snapper’s.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

We needed to update our client-facing media site. After we take pictures of a home, we create a virtual tour with them. That website was several years old, and we wanted to give it a more modern look.

SOLUTION

What was the scope of their involvement?

We initially showed Mentalstack our existing website and explained our industry requirements. There are specific guidelines for how real estate agents can advertise their home listings. We conveyed that information to Mentalstack, and their team worked within those parameters. We also shared our vision for what we wanted, and then they redesigned our website.

What is the team composition?

They have an agency structure. We first communicated with a sales representative who put us in touch with an account manager who liaised between us and the designers.

How did you come to work with Mentalstack?

I found them through a freelancer platform after an extensive search.

How much have you invested with them?

We spent around $5,000 on their services.

What is the status of this engagement?

We collaborated on this project between May–June 2020.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

Internally, we’re all happy with the product. We haven’t launched the website yet, which means we don’t yet have metrics.

How did Mentalstack perform from a project management standpoint?

We used a freeelancer platform and Zoom to communicate. Mentalstack used Figma for the design, which was another tool that we used to communicate and give feedback. It was a fairly smooth process. The project manager assigned to us was highly involved, so we didn’t have a lot of communication with the designer.

What did you find most impressive about them?

What sets them apart from the competition was the quality of their design. We didn’t give them too many parameters, and what they came up with was very impressive.

Are there any areas they could improve?

It would be helpful to directly communicate with the designer. Our communication took a little longer because there was someone in the middle.

Do you have any advice for potential customers?

The more lead time you have the better because Mentalstack’s busy. They have to wait until a designer’s disengaged from a project to be fully dedicated to a new one.

BACKGROUND

Introduce your business and what you do there.

I’m the product owner at Avanquest, a software development company and distributor.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

We’re close to launching a product so, we needed to set up a website.

SOLUTION

What was the scope of their involvement?

Initially, Mentalstack did the UI/UX design for the website, which is built on HTML 5.

What is the team composition?

We worked with two teammates: a project manager and a UI designer.

How did you come to work with Mentalstack?

We’d initially spoken to them for a branding project. However, we put that on hold and did the branding ourselves. When it came time to build the website, we remembered that we had spoken to them. 

We liked them because they were going to put a project manager into the mix, which would give us a contact point if we had any needs or wanted to do iterations. We liked that we were going to be able to have contact with someone who had business knowledge.

How much have you invested with them?

We spent around $3,500.

What is the status of this engagement?

We worked with them from June–August 2020.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

We liked Mentalstack’s work and expertise. Every Tuesday I would present the designs to the executives, and then we would give the team feedback.

How did Mentalstack perform from a project management standpoint?

They met their deadlines perfectly. Every time we needed changes or updates, they would commit to a date and complete their work on time. We had one point of contact, so it was easy to get in touch with them. 

Mentalstack responded almost immediately, usually within a few hours. We communicated via email, and we also created a Google Hangouts group, which we didn’t use very much. Additionally, we had video calls about twice a week

Our only issue was that they were in Russia, so the time difference made it complicated. Sometimes if I needed an answer in the afternoon, I would only get it the following morning.

What did you find most impressive about them?

The team was very good at coming up with a concept from scratch and having a good initial starting point. The first concept they came up with was always a good base to work from.

Are there any areas they could improve?

The only thing is that once we selected a concept, it was hard to move away from it, maybe because of the language barrier.

Do you have any advice for potential customers?

If you’re going to work with Mentalstack and are open to a completely new idea, they are really good at what they do. If you have an idea in mind, give them a detailed brief and guideline so that the team has a good starting point.

BACKGROUND

Please describe your company and your position there.

Farm Fare supports family farms and food hubs move their local agricultural products into institutional markets using an evolution in the supply chain. Our platform enables "economies of collaboration" to compete with economies of scale pervasive in the industrial agriculture market. I am one of three co-founders and serve as the CEO.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack?

We have a small but talented internal development team; however, our team is lacking design and UI/UX expertise. We hired Mentalstack to enhance the wireframes our development team created.

What were your goals for this project?

We were looking for improved UI/UX as it relates to our platform, namely the home screen and the network inventory screen. These are two critical landing pages for our users so we need them to both be aesthetically interesting while optimizing for intuitive usability.

SOLUTION

How did you select this vendor?

We submitted a proposal on Upwork and interviewed several different vendors. We spoke with Margaret, one of Mentalstack's sales representatives who was delightful, personable and knowledgeable. She guided us through Mentalstack's process and quickly provided us with a quote and timeline.

Describe the project in detail.

Margaret was very helpful in scoping out the project based on our needs, and one we agreed upon contract terms, we were assigned a project manager (Anna) and designer (Felicia). We discussed the proposal with Anna and Felicia and added them to our Slack channel, the most convenient way for our team to connect with the Mentalstack team.

We iterated several times through Figma where the designer would offer different design options, the Farm Fare team would provide feedback, and the design would be updated. The turnaround time was always fast which was especially appreciated.

What was the team composition?

Margaret was very helpful in scoping out the project based on our needs, and one we agreed upon contract terms, we were assigned a project manager (Anna) and designer (Felicia). Anna was highly communicative both on Slack and via email, always keeping us abreast of the progress that had been made.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

They provided us with a final UI/UX design in two weeks - this was critical so that our developers could implement the designs into their development work. We are working with a tight timeframe to "go live" so working quickly was of upmost importance.

How effective was the workflow between your team and theirs?

Workflow was excellent. Due to the time difference, we would start our day with updated designs from the Mentalstack team, provide feedback and would either get another update that day or by the start of our following day. We typically used Slack and Figma to communicate.

What did you find most impressive about this company?

Mentalstack's team is very personable and responsive. When working with a start-up, flexibility and speed is critical - and Mentalstack provided us with both of those elements.

Are there any areas for improvement?

We were hoping for more creativity to add to our previously created wireframes, but understand they were limited by our timing.

We operate a social network and business platform for the cultural and creative industries and I'm the co-founder.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack?

We hired Mentalstack to expand our web portal with a webshop and to implement a payment system.

What were your goals for this project?

We aimed for seamlessly integrating a webshop that offers an excellent UX/UI and at the same time maintains the existing appearance and corporate identity.

SOLUTION

How did you select this vendor?

After reviewing several agencies, we selected Mentalstack based on online reviews, in-depth interviews we conducted with them, and a sample task to solve.

Describe the project in detail.

After a rough briefing, they started brainstorming and creating mockups that allowed us to get a first impression. In a few iterations and very good coordination we came to a perfect result.

What was the team composition?

Tailored to the rather small project volume, we worked together with a talented senior UX/UI designer and a highly qualified project manager.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Not yet, we haven't gone live with the new feature yet (we'll do the development internally). 

How effective was the workflow between your team and theirs?

The project manager we collaborated with was highly professional and effective. Additionally, we could address design-related requirements directly to the UX/UI designer which made the whole process super easy and smooth.

What did you find most impressive about this company?

They understood from the start what we were aiming for, even though our briefing was very sketchy. Their communication is great and transparent, while their way of working is extremely fast and efficient. Additionally, the effort estimates were very precise and were never exceeded.

Are there any areas for improvement?

There is little room for improvement as they are already doing very well.

For what projects/services did your company hire Mentalstack?

Design and Web Development

What were your goals for this project?

Build an MVP that we can use to test the market, get feedback and begin conversations with potential investors

SOLUTION

How did you select this vendor?

We had an existing contract with them for Design services so we continued the partnership

Describe the project and the services they provided in detail.

They developed our front & back end and deployed our project. Also developed our home page. They also did all of our integrations with 3rd party tools such as Stripe, Sendgrid and others. Also developed complex functionality such as Video/Audio within our platform.

What was the team composition?

Team consisted of front-end and back end developers, designers, Testers, QA and Dev Ops. Our main point of contact was a dedicated project manager who was our key liaison. We interfaced primarily through the PM and MentalStack dialed resources up based on deadlines, etc.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The financial impact is too early to tell as we are just in early days of our company. However, having a tangible project gives us the ability to now begin our feedback loop with customers and have demo days with investors. So for us, this is tremendous value as we have moved from ideation into practical application / deployment.

How was project management arranged and how effective was it?

Skype was the main mode of communication which was highly effective. Also, given the fact that there is a 6hr time difference, we didn't feel it at all as the team was readily available or got back to us as soon as possible. Jira is used to manage tasks which was also effective to have consistent transparency.

What did you find most impressive about this company?

There is a single point of contact. There is work being done in the background however, you don't get bogged down with who has rolled on and off the project. They have a pool of talent and they can dynamically adjust their staffing model to accommodate what is happening on the project, however, the stress of that happening was invisible to us. Our designated PM keeps everything moving seamlessly. Also, for an offshore company the English proficiency is extremely high and they also understand cultural nuances and references.

Are there any areas for improvement?

The only thing would be if your not a highly technical founder/co-founder, its important to ask questions and understand the complexities of what your building. Certain features are highly complex in nature, especially if you are integrating with any 3rd party tools, and can cause unexpected or additional effort to get right, which means it can impact your budget. It's important to discuss all of these possibilities and potential scenarios in advance.

Not yet, we haven't gone live with the new site yet as we're still working on some updates to content and our database.

How was project management arranged and how effective was it?

We had a project manager who we communicated with primarily via Slack. They were fairly effective at taking feedback and conveying it to the development team.

What did you find most impressive about this company?

They were generally comfortable working with sometimes shifting project requirements as our goals for the site evolved over the time we were working on it.

Are there any areas for improvement?

More communication about the timelines for reaching various milestones and how long modifications would require could be helpful.

    I'm happy with how the project turned out - it's well designed and once it's deployed it should be a major improvement on our current site.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

We are a career focused start up. I am the Co-Founder.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack?

We hired them to help with Design & Prototype

What were your goals for this project?

Have something tangible so that we could have next stage of conversations and really validate our idea.

SOLUTION

How did you select this vendor?

They were recommended.

Describe the project and the services they provided in detail.

They designed and developed all of the wireframes and also assisted with our pitch deck. They work in 2-week sprints so we started with discussing the idea and mind mapping the product. We then developed the wireframes by feature will allowed to iterate as we went. We had a completely working design at the end which we were able to use to see all of the functionality.

What was the team composition?

We had a designated project manager with multiple designers. We primarily interfaced with the PM only, which make it much more efficient for us. It would have slowed the process down if we had to interface with multiple parties separately.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

We are very early in the startup lifecycle so there hasn't been a direct business impact yet. However, the deliverables from this project have clearly helped us to further asses product-market fit.

How was project management arranged and how effective was it?

The project manager assigned to us was very talented. Very effective in helping us think through everything and really determine what is important and valuable. She also is extremely professional, meets with us daily to ensure everything is to our satisfaction.

What did you find most impressive about this company?

They get it. The understand the lifecycle of startups. Everything that they produce is something that adds value to the process. Where ever you are in the journey. Whether your going to raise or get feedback, their deliverables help you to accomplish your goals.

Are there any areas for improvement?

There is very little they can improve. The only improvement is make sure you are clear on deliverable timelines. They are a great agency so they are busy and you just need to have conversations upfront on how resources will be dedicated to your project.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

We provide information on the energy use of home electronic devices and are branching out into reviews and offering energy-saving ideas for consumers.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack?

Our site design was outdated - we wanted to make it easier to use, as well as incorporating some new pages/features. We hired MentalStack to oversee a complete redevelopment of the site.

What were your goals for this project?

We wanted a site that would be more usable for visitors, as well as having a CMS that would make it easier for our contributors to keep our content up to date.

SOLUTION

How did you select this vendor?

We read a number of reviews on Clutch and elsewhere and narrowed the field to 3 prospective agencies which we got bids from and spoke with. We ended up going with MentalStack because their bid seemed reasonable and we liked their approach to development.

Describe the project and the services they provided in detail.

They worked with us on the redesign of the site, including the development of a new logo/brand and wireframes + mockups of all the pages on the site. They worked closely with us at each stage to make sure that the deliverables were consistent with what we were looking for. We're just starting the technical aspect of the project.

What was the team composition?

The project team consisted of a project manager, one primary UX/UI designer and drew on additional internal design resources (e.g. illustrators) as needed. We're just beginning the technical side of the project, for which they'll provide engineers and QA.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The project hasn't launched yet.

How was project management arranged and how effective was it?

Project management was very effective, we collaborated with a project manager primarily via Slack and was extremely responsive and effective in gathering feedback and making appropriate changes.

What did you find most impressive about this company?

Mentalstack's design work, as well as their ability to incorporate feedback and changes as needed, impressed us.

Are there any areas for improvement?

Nothing comes to mind.
