# 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

### Android APK (Gitea / Obtainium)

Push to `main` → Gitea Actions builds a signed APK and publishes a Gitea
release — install via Obtainium. `android/app/build.gradle` keeps literal
`versionCode`/`versionName`; CI stamps the run number in with `sed` before
building. Keystore: `~/.android-keys/kegel-release.jks` (repo secrets
`KEYSTORE_B64`, `KEYSTORE_PASSWORD`; alias `kegel`). Beware: `expo prebuild -p android`
(used to regenerate launcher icons from `store/icons/make.js`) rewrites
`build.gradle` and drops the release `signingConfigs` block — restore it from git.

### App Store / Google Play (EAS)

Store builds run on EAS (project `@mrmen23/kegel`, profile `production`,
version source remote with auto-increment). The EAS-managed Android keystore
differs from the Gitea one, so Play and Obtainium installs can't update over
each other.

```sh
# Apple: needs an App Store Connect API key for non-interactive auth
export EXPO_ASC_API_KEY_PATH=~/Downloads/AuthKey_L9Z6F5H5B7.p8 EXPO_ASC_KEY_ID=L9Z6F5H5B7 \
       EXPO_ASC_ISSUER_ID=<issuer uuid> EXPO_APPLE_TEAM_ID=HZ6XCKM95R EXPO_APPLE_TEAM_TYPE=INDIVIDUAL
eas build -p ios --profile production --non-interactive
eas submit -p ios --profile production --latest --non-interactive   # creates the ASC record on first run

# Android: needs a Play service-account JSON with release access
eas build -p android --profile production --non-interactive
eas submit -p android --profile production --latest --key <service-account.json> --track internal
```

Listing copy, keyword rationale and screenshot generation live in `store/`
(`node store/screenshots/make.js` renders `store/screenshots/raw/*.png` into
store-sized slides). Privacy policy is served from
https://rehbock.xyz/kegel/privacy.html (source in `store/web/`). iOS dev runs
via `npx expo run:ios` from a Mac.
