Project Overview
StrideAI wanted to build a fitness app that actually solved the consistency problem — 73% of gym app users quit within 30 days. Their thesis was that personalisation was the key: if every plan, every workout prompt, and every nutrition suggestion was uniquely calibrated to the individual, drop-off rates would fall dramatically.
The technical challenge was building a real-time AI recommendation engine that could adapt plans on the fly based on user feedback, workout history, sleep data, and nutrition logs — all inside a Flutter app that worked offline at the gym.
The Challenge
Generic workout plans in existing apps led to a 73% 30-day churn rate across the industry
Nutrition tracking was manual and tedious — users abandoned it within a week on average
AI recommendations required low-latency inference on the edge for real-time feel
Offline functionality was essential — gyms often have no signal
Social features needed to motivate without creating toxic comparison dynamics
Our Solution
We built a Flutter app with a TensorFlow Lite on-device inference model for real-time plan adaptation, a Python backend for training and syncing models, and a social layer focused on personal bests rather than leaderboards.
On-Device AI Engine
TensorFlow Lite model runs entirely on-device, adapting workout difficulty and rest periods in real time based on your performance — no internet required.
Smart Nutrition Tracker
Barcode scanner with a 2M+ food database and AI meal suggestions based on macros, workout schedule, and personal goals — 3 taps to log a meal.
Personal Best Social Layer
Feed shows only your own personal bests and streaks, not comparisons to others — fostering motivation without competitive anxiety.
