ccc for Android

The phone client of ccc, a terminal app for working with Claude Code. With it you can read your conversations, send messages, approve or deny tool calls, start new conversations and check the usage limits — from your phone, privately over Tailscale. It needs a running ccc on your computer with its API turned on (how).

Install

Android 10 or newer.

1. Download ccc.apk from the latest release.
2. Open it on the phone (Android asks once to allow installs from that source).
3. In ccc on the computer run ccc api pair (or Settings → Devices… → Pair a new device) and tap Scan QR code in the app.

The app holds no secret: the one-time QR code gives the phone a token made for that phone alone.
