Flow: training that adapts while you do.
A working recreation of the interface, in the page. Escape closes it.
The problem
A plan written weeks ago doesn't know what you have today. Flow builds a useful session from your goal, your training history and the equipment you have today, and shows the load building up as you train.
The decisions
- The decision engine is plain TypeScript, tested without React Native, so the prescription logic stays inspectable.
- The app layer is deliberately thin (Expo Router, Zustand for the live session, SQLite on the device), so logging a set feels immediate.
- A front-and-back muscle map makes the session's accumulated load visible at a glance.
Out in the world
On the App Store as “Flow: Gym Workout Log”. One-tap logging, warm-ups, plate math, rest control, substitutions and set types; programs adjust across missed sessions, deloads and the equipment on hand.
Built with
Expo, React Native, TypeScript, Expo Router, Zustand, Drizzle, SQLite.
