Workout app

Where we started

A training enthusiast needs an app that is fast and focused on the essentials: to conveniently log a workout right in the gym, see their progress and track nutrition. Universal fitness apps tend to be cluttered and slow, and often work on only one platform. The client needed their own app that works on both iOS and Android, combines workout and nutrition tracking in one place and lets them monetise the content with a PRO subscription — without building twice for each platform.

What we built

MBC built a Flutter mobile app for iOS and Android from a single codebase. In the app the athlete browses an exercise library with images and video, starts a workout and logs every set in real time, tracks nutrition and body measurements, and sees their progress over time. The content and subscriptions are handled by a separate administration system (see the related project).
