We built a fitness app for tracking workouts and nutrition, with an AI coach that gives advice and estimates meal calories. Today we offer the same solution to gyms.
Challenge
Existing apps are either overcomplicated or do not support Serbian, and AI features are expensive and locked behind subscriptions.
Solution
Based on an open source project we built a customized app for Android and iPhone, in Serbian and English, with a Supabase backend, user accounts and AI features: an AI coach and calorie estimation through a language model.
Key features

Exercises, sets, weights and progress history.
AI coach
Advice and workout adjustments based on the user's progress.
Calorie estimation
