Avoca SMS Relay

ANDROID DEVELOPMENT BUILD

Start with a test phone and synthetic SMS.

The Android app remains a development build. No public APK download or Google Play listing is offered on this website.

Android

The build targets Android 15 and uses Android 8 or later APIs. Device compatibility is unverified. Incoming SMS requires installer allowlisting and runtime permission. SMS destinations also need sending permission and a default SMS SIM. Notification rules need separate opt-in and Android notification access.

Google Sheets

The project owner must enable the Sheets API, configure OAuth consent and register the Android package plus signing certificate in Google Cloud. The app requests drive.file access and creates a dedicated spreadsheet. It does not request access to every spreadsheet.

Destinations

HTTPS destinations support optional encrypted Basic Auth and headers without following redirects. SMS destinations require an international number. Use the local rule tester first; synthetic destination tests actually send data and SMS tests may incur carrier charges.
