Codync turns coding agents running on a Mac or Linux computer into persistent bots you can message from an iPhone or iPad. Give each bot its own project, agent, and standing instructions; send a task, follow its live activity, and inspect commands or file changes before approving them. The app also supports routines, group conversations, voice calls, notifications, widgets, and Live Activities. A separate Codync host must run on your computer. The developer says code and conversations stay on that host; its optional remote relay forwards end-to-end encrypted traffic. The iOS app is free, has no listed in-app purchases, and requires iOS 26 or later. Apple’s privacy label says the developer reports no data collected.
