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

Ported from the PWA at health.rehbock.xyz/app/ (repo marcus/health.rehbock.xyz, app/index.html); charts are react-native-svg, tap a bar for the night/week detail.

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 (alias health), 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 once a Gitea release exists).

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.
