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 within Spaces, invite people, view participants, and post in human-only conversations.
  • Recover interrupted Space setup and invitations more reliably, with stronger participant permissions.
  • Get started with a shorter setup flow, then click your Chief of Staff's avatar to change its name or look.

Desktop

  • Choose your approval mode when your agent first needs to take a consequential action.
  • Set up integrations conversationally with your agent.
  • Your saved composer model stays selected while provider model lists load.
  • Restore appearance defaults and access account controls from the lens rail.

Reliability

  • Open windows refresh when background sync brings in changes.
  • Sync recovers more reliably after interruptions and retains changes made while syncing.
  • Settings are better protected against interrupted saves and simultaneous changes.
  • Slack replies stay in their threads, and dropping folders into chat no longer triggers an import error.
