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

  • Get started through a conversational Welcome with provider setup and saved history.
  • See participant activity in text threads.

Desktop

  • Find Home beneath the Chief Think Agent, with nested Spheres and direct access to Agents and Chats.
  • Keep Home or the Chief Think Agent selected when opening threads from its sidebar.
  • Access shared Spheres from a dedicated rail and keep Sphere tree branches expanded between visits.

Sphere Sharing

  • Review history-sharing consent and owner computer requirements before sharing a Sphere.
  • See sharing preview and confirmation progress, with errors you can retry in place.
  • Choose how to handle content when deleting a Sphere you created.

Reliability

  • Sign-in continues through brief connection failures and ignores outdated results.
  • Queued messages and collaboration work recover more reliably after offline restarts.
  • Completed responses stay preserved across device sync, with messages kept in chronological order.
  • Creation and artifact saving show pending progress, including in long forms.
