Cognition launches Devin iOS beta 'Cog' on September 23 via Apple TestFlight

On September 23, Cognition AI's coding agent Devin appeared as a closed TestFlight beta called 'Cog for Devin,' open for signup on iOS 16 and above. The app's positioning is 'step away from your computer and write some code,' continuing Devin's coding agent reach onto mobile devices, in contrast to T3 Code which already ships a mobile app.

The rollout follows Cognition's June integration of Windsurf under the Devin Desktop brand and is consistent with the company's broader IDE product matrix strategy.
