The Challenge.
Most fitness apps fail users after the first two weeks — because generic plans don't account for real life: missed workouts, changing energy levels, and evolving goals. We needed to build an adaptive engine that would keep users engaged by meeting them where they actually are, not where they hoped to be.
WHAT WE BUILT
Adapts to you.
Not the other way.
We trained a lightweight TensorFlow Lite model on anonymized workout data to predict optimal workout intensity and rest periods. The model runs entirely on-device — no server call, no latency, no privacy risk.
Social challenges and streak mechanics were layered on top of Firebase to drive retention without dark patterns — everything is opt-in, and users can pause challenges without losing progress streaks.
