A small Android app for capturing electricity meter readings from photos and syncing them to a Google Sheet.

What it does

• Camera tab — take a photo of the meter; the app stores it locally.
• Photos tab — browse captured photos, see OCR/sync state per photo, tap to view fullscreen with pinch-to-zoom.
• Readings tab — list of recognized readings.
• Settings tab — Gemini API key, Google Sheet ID, sheet name, and a service account JSON; includes a step-by-step Russian setup guide.

Under the hood, photos are sent to Gemini for OCR (meter number, tariff, kWh, reading date), and the parsed results are appended to a Google Sheet via a service account.

Build

See Makefile:

• make apk-split — release APKs split per ABI (install app-arm64-v8a-release.apk on a modern phone, ~19 MB).
• make apk — universal release APK (~52 MB, all ABIs).
• make run — run on a connected device with hot reload.
• make help — list all targets.
