Feedback summary: 

The functional and quality prototype performed as needed. Their designs were both practical and appealing. App’n’roll ensured its timely delivery with proactive communication and strict adherence to deadlines. They created an effective process for the remote and international partnership.

BACKGROUND

Introduce your business and what you do there.

I’m the CEO and co-founder at AutoSeca, a water management company. We’re developing a leak detection and water management system that’s non-invasive to plumbing. We’re focused on commercial and industrial buildings.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with App’n’roll?

After we got to a certain part of our technical development, we needed to be able to show our prospective customers how information, data, and notifications would appear. Our organization needed an app, but we weren’t ready to develop one because we didn’t have the product completed. We then hired App’n’roll to develop a prototype to demo on our phones to customers.

SOLUTION

What was the scope of their involvement?

I outlined our vision for the app. Since I have a web-based background, my description didn’t align with how people use mobile apps. As a workaround, App’n’roll took my skeletal and minimal input to develop the complete prototype. During development, the team educated me on best practices. To demonstrate the app’s flow, my engineering team selected limited data to incorporate on the prototype.

What is the team composition?

I interfaced primarily with two people and there were others behind the scenes. Tomasz (CEO/Co-Founder, App’n’roll) was the first person I talked to and did the contracting with. There was a woman who was doing the design and the development; she had a team working behind the scenes.

How did you come to work with App’n’roll?

I got an unsolicited email from App’n’roll; their offerings matched the services I needed for the app. I have no idea why I opened it because I don’t usually open those things, but I'm glad I did. Although I didn’t look at any other companies, I was still apprehensive about the geographical distance.

How much have you invested with them?

We spent $15,000.

What is the status of this engagement?

We worked with them from September–October 2017. We plan to engage them again next month for more technical development to create the real app.

RESULTS & FEEDBACK

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

I was hesitant to start the app because we didn’t know how App’n’roll would present the data. I’m very particular and needed a vendor that could tell me when I was wrong, but also listen when I wasn’t.

I found their responsive service and quality deliverables impressive; the prototype felt like a real app. The prototype became the first look and feel for the company beyond the logo.

How did App’n’roll perform from a project management standpoint?

The team performed well and often chased me for approvals or input. They managed the project on my schedule even though my delayed responses made that nearly impossible. But if I was delinquent on delivering something, the team never used that as an excuse for being late. They’d be on me and explain that deliveries relied on my response times. The physical distance was never an issue; it was like they were right next door.

What did you find most impressive about them?

The creative visuals stood out. The designs were also practical because App’n’roll remained focused on the objective. That balance between aesthetics and function distinguished the team from other vendors that think only about the former.

Are there any areas they could improve?

No, I can’t think of anything.

Do you have any advice for potential customers?

Don’t be afraid of a remote partnership. The distance had no impact on the quality or the service. The pricing was incredibly competitive as well.

Project summary: 

App'n'roll developed a native Android application as a copy of an existing iOS app, using a supplied API and designs. They continue to work on app maintenance.

The Review
Feedback summary: 

The Android application was developed with a high level of quality, receiving only 5-star reviews from its users. The team was dedicated, performing professionally, and meeting the majority of deadlines.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO of a fintech company in the wealth management space.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with App’n’roll?

We already had an iOS app and we needed to make a copy of it for Android.

SOLUTION

What was the scope of their involvement?

They developed a native Android version of our iOS app, using an API and some designs supplied by us. They made some tweaks to the designs, but they didn’t fully modify them; the majority of this project was development. They had some good ideas related to the differences in user behavior between iOS and Android, which they used to translate our app in a nice way, but they didn’t build any features particular to this version.

They’re fully in charge of app maintenance. We send them new requests every two weeks, and they’re fast in developing them.

The app has a longer than normal signup flow that requires users to fill a questionnaire and upload documents. On the other side, there is a dashboard where people can log in, contact support, and perform a lot of other actions.

What is the team composition?

We worked with five people from their team on this project, including a product owner and three developers. I was mainly in contact with two of them.

How did you come to work with App’n’roll?

I approached around five providers at the time, both local and international. I sent each one a small test that required them to build a login screen and other small items. App’n’roll was the only one able to do it within the time scope, and to figure out the small quirks I’d left for them. Our first contact with them was through a common partner.

How much have you invested with them?

We spent around $20,000 on this first project with them. The overall cost so far is around $50,000. We’ve had an ongoing collaboration for the last one and a half years, with weekly invoices from App’n’roll.

What is the status of this engagement?

We started working with them in February 2017. The Android app was launched around April of the same year.

RESULTS & FEEDBACK

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

There haven’t been any major complaints about the app; there were some minor issues, but this is normal for software development. We’ve seen only 5-star reviews on our trust website as well as on Google Play.

How did App’n’roll perform from a project management standpoint?

I’m pleased with their performance. I have direct contact with the developers, and because I’m a developer myself, it’s been easy for us to communicate.

They had a busy period on one occasion, leading to a two-week wait. Other than that, they work on our new feature requests in one or two days. It’s crucial for us to deliver fast, so it’s nice they can do that.

We’ve had a few calls on Skype, but the majority of the communication has been through Slack.

What did you find most impressive about them?

They did a remarkable job with the first release and with overall testing. They did code reviews on their side, even though I told them it wasn’t necessary; it’s a nice approach that’s not offered by many other providers.

They also have good speed; they answer and learn fast. I’m the bottleneck the majority of the time.

Are there any areas they could improve?

I would’ve told them if there was anything I was unhappy with.

Do you have any advice for future clients of theirs?

The better the client is at scoping and telling the team what they’re looking for, the easier it is for them to figure out what to do.

Feedback summary: 

Users have reviewed the solution positively. App’n’roll’s high-level communication and expert use of project management tools, along with their attention to detail, made the engagement successful. Their commitment to success was evidenced by their comprehension of underlying vision.

BACKGROUND

Please describe your company and your position there.

I’m the CEO and co-founder of Survicate.com. We’re a survey and lead pre-qualification tool for small and midsize businesses that’s integrated with Marketo, Salesforce, Eloqua, and Hubspot.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire App'n'roll?

After successfully using venture capital (VC) funding to get started, we decided to scale up.

What were your goals for this project?

We needed to develop a minimum viable product (MVP) of our software tool. The tool enables users to collect feedback from their customers across all digital touchpoints using a variety of surveys including targeted website, one-click email, and Net Promoter Score (NPS). We also planned to utilize feedback widgets and questionnaires.

SOLUTION

How did you select this vendor?

We met each other through a combination of our personal professional networks. We were looking for a company who was business-minded, design conscious, and tech-savvy.

Can you go into detail about the services they provided and the scope of the project?

We focused on building the MVP so that we could start testing the core functionalities with real users. Since I don’t have a technical background myself, I shared my business idea from a user perspective which App’n’roll then translated into the product backlog, which is a list of tasks that need to be done that was later used by their developers. App’n’roll was responsible for translating the idea into product backlog, writing technical requirements, development, testing, system administration, and several other tasks. They also contributed business consulting, fundraising, and meetings support with potential clients.

What was the team composition?

The team was small and comprised of highly skilled developers, designers, a marketer, and a project management.

RESULTS & FEEDBACK

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

We’ve received a lot of positive feedback from a number of large companies who are happy with our tool.

How was project management arranged and how effective was it?

Our work was both effective and efficient thanks to a combination of productivity tools and consistent communication.

What did you find most impressive about this company?

I found their professionalism and attention to detail to be their most impressive qualities. They were wholly engaged in the project and understood our vision and intentions.

Are there any areas where they can improve?

We were satisfied with the work App’n’roll did to make us what we are today. Nothing immediately springs to mind in terms of areas that could be improved upon.

App'n'roll was able to finish the project about 40% quicker than the client's previous agency. The client was happy with App'n'roll's constant line of communication and that the company is filled with self-starters.

BACKGROUND

Introduce your business and what you do there.

I am a Technology Consultant at a health care and senior care coordination platform.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with App’n’roll?

We needed an agency to help us continue development of a software platform.

SOLUTION

What was the scope of their involvement?

The software tests user behavior. They took over development from a previous service provider and are currently fully responsible for the software development of the platform. They used Ruby on Rails to develop it. They used Invision for the design of the app, and did some independent software development following our feature requests. They were proactive and offered a valuable challenge to features, and suggested their own ideas for our consideration. We discussed feature requests, time and cost estimates, and specifics of proposed solution.

How did you come to work with App’n’roll?

We knew them through a personal connection. I feel they provided great quality of work for a good price and trust due to our personal connection.

How much have you invested with App’n’roll?

The whole project was between $50,000 and $200,000.

What is the status of this engagement?

The project is ongoing.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

We had initially thought that the project would take over a week. App’n’roll was able to complete it within just 2 days for no additional charge. We were happy about that. That made them about 40% faster than our previous provider.

How did App’n’roll perform from a project management standpoint?

They are really great. They have excellent communication that is maintained almost 24/7. They used Trello for messaging, and Mailchimp and Mandrill for emailing.

What did you find most impressive about App’n’roll?

The quality of their code, speed, and ability to work independently were all great. They work fast and are self-starters. They will suggest necessary changes by themselves and are responsive to business needs. They were very smart and made modern improvements of existing codebase and design, which we appreciated.

Are there any areas App’n’roll could improve?

They could have had even better sensitivity to our current business needs and our priorities and budgets. That being said, this is a minor issue.

RESULTS & FEEDBACK

The Android app is a must because of the market share between Android and Apple. That being said, I'm still struggling with the limitations of Android’s digital audio capacities, which are far less powerful than Apple’s.

How was project management arranged and how effective was it?

Their team is quite efficient at providing feedback and asking questions that get straight to the point.

What did you find most impressive about this company?

Their speed is outstanding.

Are there any areas where they can improve?
