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

  • Collaborate in Spaces with invitations, participant profiles, replies, reactions, and conversation search.
  • Browse beside each conversation with multiple tabs, a detachable window, and page annotations you can send into chat.
  • Use Auto model selection with provider preferences and usage limits.

Desktop

  • Dictate prompts with recording controls and clearer setup guidance.
  • Rename conversations, keep your reading position as messages arrive, and jump to the latest messages.
  • Manage notifications in an inbox and choose whether macOS alerts appear while ThinkOS is focused.

Companion Sync

  • Pair devices with persistent manual codes, native copy controls, and clearer connection status.
  • Keep a fresh pairing code available after the first phone connects.
  • Keep Space read state synchronized across devices and discover newly shared Spaces without restarting.

Reliability

  • Space posts can be accepted locally while offline, with a clear pending state until delivery.
  • Recover interrupted Space invitations and synchronization while preserving participant names, photos, and conversation deletions.
  • See fewer stale running indicators and keep unsaved settings intact during background refreshes.
