Weight-loss activity tracking and consultation at your fingertips

How to create a fitness app that won’t get boring after a week?


We helped users unleash the fitness potential with an app designed for longevity and results. Our development team addressed the challenge of high user churn by creating a personalized workout experience that adapts to your rhythms, offers expert guidance, and delivers unwavering motivation.

About the project

When dealing with startups, we are usually very picky. Our priority is to cooperate with startup founders who not only have a sustainable budget for a project, but rather have a pain-relieving solution in their minds.

This case describes our cooperation with one of such startups. We partnered with a well-funded startup in the health-related sector.

The Client came to us with an idea to build a weight-loss mobile application based on personal metrics. The project had its challenges and nuances, which only strengthened our interest in it.

Client's challenges

  • Our Client needed to collect and analyze personal health metrics fed by wearable devices

  • The project required direct integration with wearable devices (such as the Garmin API, Strava, and other proprietary devices with publicly available APIs).

  • The Client wanted to collect the information in centralized storage, analyze it, and produce historical and predictive analytics.

  • The requirement was to set up a communication channel for consultants and their patients via internal text/audio messages and video calls regarding their progress. These sessions were also required to be recorded for future reference.

Project details

Our goal was to empower the Client with a cutting-edge solution for collecting and analyzing a range of personal health metrics, including calorie expenditure based on physical activity, heart rate information, weight changes, and more. The face-to-face meetings in Toronto allowed us to create a customized UX/UI design, right in front of the Client's eyes, ensuring an aligned development process with no room for misunderstandings.

To ensure a smooth collaboration, our UI/UX designer held personal meetings with the Client in Canada. During these sessions, we worked together to prioritize the project's requirements, resulting in the creation of effective UX/UI designs and prototypes. Through active communication and collaboration, we seamlessly blended the Client's vision with our technical expertise to build a highly intuitive and user-friendly interface.

As a software development team, we stuck to our standard operating hours of an 8-hour workday for 5 days a week. Our team successfully delivered a cross-platform mobile app that integrates with various wearable devices, a data-driven backend, and robust reporting features. The challenge of synchronizing data across all devices was met with well-thought-out architectural decisions. To ensure quality and efficiency, we employed a comprehensive QA strategy using TestCafe, BrowserStack for automated testing and SoapUI for API testing with automated runs.

I have been using the app for almost a year and I have only positive emotions. Thanks to it, I have grown to love workouts and healthy eating so much that I even find time for it on vacation!

I really liked it! The workouts were fun, and most importantly, the trainers were responsive and supportive. I was also able to discuss my situation with excess weight with a qualified doctor.

All categories are thought out—legs, back, neck.... I understand why there was no motivation before, but now the system of reports, nutrition charts, regime, and a coach won't let you relax.
