A fitness tracking app that turns raw workout data into a plan you'll actually follow.

Gain Track is a cross-platform mobile app built with React Native, backed by PostgreSQL and layered with AI-driven coaching — shipped end-to-end to the Apple App Store.

Built with React Native, for both platforms

One TypeScript codebase powers Gain Track on iOS and Android, sharing business logic, navigation and design system across platforms while still feeling native on each.

PostgreSQL-backed, built to scale with your data

Every workout, set and rep lands in a PostgreSQL database designed for fast historical queries — so progress charts, streaks and personal records stay accurate as your training history grows.

AI that actually reads your training data

Gain Track uses AI to turn weeks of logged sets into plain-language coaching: what to adjust, when to deload, and where you're plateauing — instead of just showing you another chart.
