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

  • Invite people to Spaces, manage participants, and create human-only conversations within existing Spaces.
  • Get started with a shorter AI setup flow, then click your Chief of Staff's avatar to change its name or appearance.
  • Hand work to an agent with an @mention and see which agent authored a response.

Desktop

  • Choose an approval mode when your agent first needs to take a consequential action, with clearer guidance for system permissions.
  • Your saved composer model stays selected as provider model lists load.
  • Restore appearance defaults and access account controls from the navigation rail.
  • Dropping a folder into Workbench chat no longer triggers a folder-read error.

Reliability

  • Agent turns can continue beyond thirty minutes.
  • Open windows refresh after background sync, with better recovery of interrupted connections and changes made during synchronization.
  • Space invitations and setup recover more reliably after interruptions, with stronger participant permission checks.
  • Settings changes are better protected against crashes and simultaneous updates, and Slack replies stay in their threads.
