Your coding agent shouldn't wait for you to get back to your desk. A task can run for an hour and then stop five minutes in to ask for permission or a decision. Happy lets you answer from your phone, and the same agent carries on in the same repository with the same tools and context. Happy is the mobile app for Claude Code and Codex. The agents keep running on your own computer, and your phone is how you start them, steer them and review their work. WHAT YOU CAN DO FROM YOUR PHONE • Start a new session or pick up one you began at your desk • Get notified when an agent needs input or finishes • Approve or deny permission requests, or let a session run in Auto mode • Choose the model and reasoning effort from the providers set up on your computer • Review changes: a file list, colored diffs, and the full set of changes on a branch • Attach a screenshot or photo to your prompt • Browse sessions in one list or grouped by project, with each checkout's chats as tabs • Open a side chat next to a session without losing your place • Drafts follow you between your phone and your computer HOW IT WORKS Happy runs on your computer, and this app connects to it. 1. Install Happy Desktop from happy.engineering, or if you prefer the terminal, run: npm install -g happy 2. Create an account in the app. You don't need an email address or a password. 3.

ReceptionRating · Positive reviews · Number of ratings

Happy holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Happy has 1K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 72% of Happy's written reviews are positive against 100% of TARS for OpenClaw's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Happy ships an update weekly, TARS for OpenClaw every 5 weeks. The most recent releases landed on October 14, 2026 and October 1, 2026 respectively.
