ClosedLoop

ClosedLoop is a workout logging app built around one principle: your data stays on your device.

No account required. No cloud sync unless you want it. No ads, no tracking, no analytics. Just a clean, fast app for logging your training and watching yourself improve over time.

— LOG YOUR WORKOUTS
Start a session, add exercises, and log your sets with weight and reps. Sessions are grouped by date on the home screen calendar so you can see your training history at a glance.

— TRACK YOUR PROGRESS
The progress screen shows charts for every exercise you have logged data for. Switch between max weight and total volume over time, with your personal record marked on the chart.

— PLAN YOUR TRAINING
Create multi-week workout plans manually, or let ClosedLoop generate a personalised plan for you using a locally hosted Ollama AI model — your data never leaves your network.

— YOUR DATA
Export or import the SQLite datbase the app uses.

— BUILT FOR PRIVACY
ClosedLoop requests the INTERNET permission only to support the optional local Ollama features. It is disabled by default. If you never configure it, the app makes zero network requests.
