The challenge

Gym members often track workouts in notes apps, and coaches cannot see what was actually done. Programmes get handed out on paper and lost. Both sides needed one shared place for the plan and the results.

Our approach

We built the member app in React Native and synced activity from HealthKit and Google Fit. Coaches get a web dashboard on the same Node.js API, so programme changes reach members straight away.

01
Live set tracking
Log reps and weight as you lift, with rest timers and the previous session shown alongside.
02
Streaks and progress
Charts show strength and volume over time, and streaks reward turning up consistently.
03
Coach programme builder
Coaches build multi-week programmes from an exercise library and assign them to members or groups.
04
Health data sync
Steps, heart rate and workouts flow in from HealthKit and Google Fit with the member's permission.
