- react-native-health-connect (config plugin, minSdk 26, 11 read perms) - sync-on-open + manual sync: incremental via server watermark, chunked POST to /api/health/v1/fitbit/sync (HR, resting HR, HRV, SpO2, resp rate, steps/distance/kcal/floors dailies, staged sleep sessions) - Fitbit screen: steps/RHR/HRV/SpO2 tiles + daily charts + sleep list + per-stream record counts (answers the which-types-does-Google-Health- share question empirically) - Sleep tab now merges Fitbit Air nights (wins over older sources) - Today screen Fitbit card Server side (deployed separately on VPS): hc_samples/hc_daily/hc_sleep tables + sync/latest/summary endpoints in health-api; Caddy routes POST /api/health/v1/fitbit/* behind the same basic_auth.

health-app
Cross-platform (iOS + Android) Expo app — native front end for the private health dashboard at https://health.rehbock.xyz.
The app is a pure client: all data lives on the server and is fetched live over
HTTPS with HTTP Basic auth. Nothing is stored on the device except the auth
token (in the platform keychain via expo-secure-store).
Screens
| Screen | Data source |
|---|---|
| Today | overview cards + clinical priorities (health-meta.json) |
| Blood | /api/health/v1/biomarkers + /draws — search, flags, sparklines |
| Sleep | /api/health/v1/sleep + sleep-data.json — stacked stage chart |
| Train | /api/health/v1/workouts — weekly volume chart, expandable sessions |
| Body | dexa-scans.json — DXA summary with deltas, regions, indices |
| Mind | /api/meditation/v1/stats + /sessions |
| DNA | ancestry-traits.json — 99 AncestryDNA traits |

Development
npm install
npx expo start # scan the QR with Expo Go (iOS or Android)
Log in with the same Basic-auth credentials as the website.
Android release APK
Signing expects (auto-skipped if absent, falling back to the debug key):
- keystore
~/.android-keys/health-app-release.jks(aliashealth), or$HEALTH_KEYSTORE - password in
~/.android-keys/health-app-release.password, or$KEYSTORE_PASSWORD
The signing config is injected by plugins/with-release-signing.js at prebuild.
npx expo prebuild --platform android
cd android && ./gradlew assembleRelease
# → android/app/build/outputs/apk/release/app-release.apk
Install on GrapheneOS by copying the APK over, or via Obtainium.
CI (Gitea Actions)
Every push to main runs .gitea/workflows/release.yml: prebuild →
signed arm64 APK → Gitea release tagged v1.0.<run_number>, APK attached.
app.config.js stamps VERSION_CODE/VERSION_NAME from the run number so
each release installs as an upgrade (Obtainium-friendly).
Repo secrets: KEYSTORE_B64 (base64 of the jks), KEYSTORE_PASSWORD.
iOS
No Mac is available in this setup, so there is no local iOS build. Options:
- Expo Go (zero setup):
npx expo start, scan the QR from the iPhone. - EAS Build (real install):
npx eas build -p ios— needs an Apple Developer account; produces a TestFlight/ad-hoc build in the cloud.
The ios.bundleIdentifier is already set to xyz.rehbock.health.
