- Buddy 2.1 is a free, open-source Android app
- It lets AI coding agents such as Claude Code, Codex and OpenCode use the phone directly
- The app can read the screen, tap buttons, type text, scroll and open other apps
- It is early-stage software, and accessibility access plus sensitive data need care

A free, open-source Buddy Android app called Buddy 2.1 lets AI coding agents interact with a smartphone without a PC. The agents named are Claude Code, Codex and OpenCode.

In this article we set out what the app is said to do, and why the permissions matter. Here is everything you need to know.

What the Buddy Android app can do

The description says the app can read the screen, tap buttons, type text, scroll and open other apps, so an agent can automate everyday tasks on the phone itself.

It is still early-stage software. Anyone who installs it is told to be cautious about accessibility permissions and about sensitive information on the device. An app that can see the screen and tap controls can also reach banking apps, messages and passwords if those permissions are granted.

Why it matters

Coding agents have mostly lived on a computer. Putting that control on a phone changes who can run them, and it widens what a bad permission setting can expose.

• The app is free and open source
• Version 2.1 is the release named here
• Claude Code, Codex and OpenCode are the agents named
• No PC is required for the phone-side control described
• The software is early-stage

What users should check first

1. Read which permissions the app asks for, especially accessibility.
2. Do not grant access you would not give a person holding your phone.
3. Keep banking, identity documents and passwords away from a tool this new.
4. Remember that open source does not, by itself, mean the install is safe for every user.

What happens next

Later versions may limit what the agent can see. We will update this article if the project publishes a safer default or a stable release note.

Our verdict

The Buddy Android app is a free way for Claude Code, Codex and OpenCode to tap, type and read an Android screen. Treat it as early-stage, and be strict about what it is allowed to open.
