# Kegel

Pelvic floor trainer for sexual performance — a free, local-only take on what
Stamina was before it went paid. Expo / React Native, Android + iOS.

## How it works

A session is four guided blocks driven by a step timer with haptic cues:

1. **Holds** — 8 × squeeze-and-hold. This is the progressive-overload driver:
   holds start at 5s and grow **+1s every 3 completed sessions** (capped at
   30s). Manual ±1s adjustment in Settings.
2. **Pushes** — 5 × reverse kegel (gently bear down). Scales at half the rate
   of holds, capped at 12s.
3. **Quick squeezes** — 10 × 1s burst contractions with 1s release.
4. **Quick pushes** — 10 × 1s burst pushes with 1s release.

Progress (session count, difficulty adjustment, completion history) lives in
AsyncStorage — no server, no account. The home screen shows your **day streak**
(alive until a full day is missed), best streak, and a two-week activity strip.

## Layout

- `src/app/` — expo-router screens: `index` (home), `session` (timer), `settings`
- `src/lib/workout.ts` — pure session-plan + progression logic
- `src/lib/streak.ts` — pure streak / calendar-day logic (tested)
- `src/lib/store.ts` — tiny local store persisted to AsyncStorage
- `android/` — committed prebuild output; CI builds it directly

## Development

```sh
npm install
npm start            # Expo dev server
npm run typecheck
npm test             # node --test over src/lib/*.test.ts
```

## Release

Push to `main` → Gitea Actions on the desktop runner (`runs-on: desktop`,
never the VPS) builds a signed APK and publishes a Gitea release — install via
Obtainium. Keystore: `~/.android-keys/kegel-release.jks` (repo secrets
`KEYSTORE_B64`, `KEYSTORE_PASSWORD`; alias `kegel`). iOS runs via
`npx expo run:ios` from a Mac.
