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 conversational provider setup in a persistent Welcome that preserves your setup history.
  • Browse Spheres, Agents, and Chats from the new Home view, with a separate rail for shared Spheres.
  • See participant activity in text threads and clearer unread indicators.

Desktop

  • Keep Home or the Chief Think Agent view selected while opening threads from its sidebar.
  • Sphere tree branches remember their expanded state.
  • Your account avatar stays consistent, and your monogram color is preserved after signing out.

Sphere Sharing

  • Review clearer sharing labels, history consent, and owner computer requirements before sharing.
  • See immediate sharing preview progress and retry failures in place.
  • Sphere creators can delete a Sphere with a choice about its content, with removal carried through to channels and guest copies.

Reliability

  • Queued messages and saved channel work recover more reliably after offline restarts, with Slack recovery preserving delivery order.
  • Synced conversations preserve message chronology and completed responses.
  • Sign-in handles brief connection failures more reliably, and automatic update progress refreshes correctly.
  • Sphere removal no longer gets stuck in an endless refresh.
