Claude Code on your iPhone. 100% free.
Claude Code keeps running on your own Mac, Windows PC or Linux machine, with the Claude login it already has. Codync turns it into named bots you message, approve and follow from your iPhone, for free.
Claude Code as named bots
Give each Claude Code bot a name, a project folder and instructions. Each keeps one ongoing chat, and you see its final reply for every turn.
Approve from your phone
When Claude Code wants to edit a file or run a command, the request comes to your iPhone: allow once, always allow or deny.
Pinged only when it matters
A notification when a bot needs you or finishes, plus a Live Activity and the Dynamic Island while it works.
Your limits at a glance
Your Claude 5-hour and weekly limits, read locally from Claude Code, show on the phone, in widgets and in the Mac menu bar.
