+# Hermes Progress
+
+## Done
+
+- Android: switched the app to the Hermes package/name, backed the UI with the backend, added server clock sync, and buffered analytics flushing.
+- Android: localized the remaining language labels so the locale toggle and session language row no longer show hardcoded `EN`/`SV`.
+- Backend: added `server_time` to `/health`, added audit logging, and added smoke coverage.
+- iOS: switched the source to the backend-backed flow, added clock sync, analytics flushing, and localized the remaining language labels.
+- Verified Android with `./gradlew :app:assembleDebug`.
+- Verified backend earlier with `cargo test`.
+
+## Next
+
+1. Continue from the current plan phase and keep closing out the remaining localization and polish items.
+2. Keep Android and iOS behavior aligned with the backend contract.
+3. Add or verify iOS build coverage if an Xcode project becomes available.
+4. Continue expanding tests around session, odds, settlement, and analytics flow as the app grows.
+
+## Notes
+
+- English and Swedish are required from day one.
+- The server remains authoritative for lock time, odds acceptance, and settlement.
+- iOS build validation is still unavailable here because there is no Xcode project in `mobile/ios-app`.
