Features
- Log fast. Sets and reps, timed holds, distance, intervals and check-off exercises. Warm-ups, drop sets, supersets, RPE, notes and last session's numbers beside each set.
- Rest timer with sound and vibration, even when the phone is locked.
- Plates per side for barbell work, with your own bar and plates.
- PR badges the moment you beat your best weight, estimated 1RM or hold.
- Plan and track. A 12-week heatmap, weekly templates with local reminders, muscle sets, and stats for volume and every lift.
- Measurements and progress photos that stay on your phone.
- Your data. Export everything to one ZIP, back up to a folder you choose, and import from Strong, Hevy, FitNotes, StrengthLog or a spreadsheet.
- Works with every radio off. Android release builds have no internet permission.
Build it
The app runs in a development client, not Expo Go. With mise and the Android SDK in ~/Android/Sdk, run mise install once (it provides JDK 17 and sets ANDROID_HOME), start an emulator or connect a phone, then:
npm install
npm run android
After the first build, npm start is enough until native code or app config changes. npm run typecheck, npm run lint and npm test are the checks CI runs; npm run e2e runs the Maestro flows against an installed build.
A standalone build bundles the JS and needs no Metro server: npx expo run:android --variant release. There are no over-the-air updates; every change ships in a new build.
CLI
The CLI runs the app's domain operations against a local SQLite file. It needs Node 22.18 or later.
npm run cli -- /tmp/nicereps.sqlite seed
npm run cli -- /tmp/nicereps.sqlite totals 2026-09-30
npm run cli
The last command lists every command.
