If the "on the go" experience is important to you, i.e. you actually want some care and intention put into the phone experience. There are 4 apps I'm aware of:

- Happy Claude Code Client: open source (MIT) effort for a quality mobile app

- Omnara: closed source mobile app, $9/month

- CodeRemote: closed source mobile app, $49/month

- Kisuke: closed source mobile app, private beta, unknown price

If you know of others, I would appreciate a PR to update the table I put together, or just let me know and I'll add it.

There are more more desktop apps, probably because those are easier to design.

OpenAI Codex is available on the mobile app.
