iPhone and iPad through TestFlight

  • ThinkOS has completed Apple's TestFlight review and is approved for public testing. We're distributing the iOS app through TestFlight for now because we're making rapid changes and want to deliver fixes and improvements quickly before the full App Store release.
  • Install Apple's free TestFlight app on your iPhone or iPad if you do not already have it, then open the ThinkOS public TestFlight link on that device and tap Accept or Install.
  • New ThinkOS builds appear in TestFlight as they are released. You can update manually or enable automatic updates in TestFlight. Expect frequent changes, occasional rough edges, and features that may move while the early release develops.
  • TestFlight builds are available for up to 90 days. We plan to keep a current build available, but if a build expires, return to TestFlight for the newest one.
  • Feedback is part of this early release: send notes from TestFlight, including screenshot feedback when useful, so we can reproduce issues and improve the next build.

Highlights

  • Create conversations in Spaces, invite participants, and respond with reactions and replies.
  • Find messages with Spaces search and jump to the latest conversation activity.
  • Use Auto to select models for desktop and cloud work, with routing preferences and provider usage controls.

Desktop

  • Dictate prompts in Orbit and Spaces with recording controls, clearer feedback, and setup guidance.
  • Switch computers within existing threads and edit or delete routines from the thread drawer.
  • Manage alerts through a notification inbox with dismissal and granular preferences.
  • Personalize your Chief of Staff's name and appearance from its avatar.

Reliability

  • Keep Space read state and encrypted notification preferences in sync across devices.
  • Retain your reading position as conversations update, with more reliable image attachments and previews.
  • Recover more reliably from stale Claude sessions, sign-out, and interrupted cloud setup.
  • Preserve newer local edits during sync and improve notification catch-up.
