What the app does
Built to run your own gateway
Native Android app
Kotlin + Jetpack Compose: phone OTP, OTP-capture foreground service, on-device controls only for BusySMS.
Your phone as a gateway
Enroll a phone you own and it becomes a gateway device on your org — capturing only verification-style codes, not your personal inbox.
SMS inbox + status
See each code, detected service, and whether use succeeded (register, login) or failed (already registered, expired).
Read by API & MCP
List your devices, pull captured OTPs, or long-poll for the latest code straight from your scripts and agents.
Scoped API keys
Per-org API keys resolve to your own devices only. $5 / verified number / month, 7-day free trial.
Persistent notification
While the gateway is active, Android keeps a clear notification so you always know capture is on.
You control start / stop
Capture is explicit. One-tap stop. Consent explains what is captured before you continue.
