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, replies, reactions, conversation search, and read state that follows you across devices.
  • Browse beside your conversation with multiple tabs, a separate window option, and page annotations you can share in chat.
  • Use Auto model routing with provider preferences and usage limits, and restore saved task models after restarting.

Desktop

  • Queue follow-up messages or steer an active chat while keeping current tool activity visible.
  • Create local Spheres from the New menu and rename agents directly from their profile names.
  • Dictate prompts with clearer setup guidance, recording controls, and fixes for microphone permissions and silent input.

Companion Sync

  • Receive paired conversation messages and status updates with less delay and more reliable delivery.
  • Pair devices with persistent codes, clearer connection status, and controls that stay stable during background checks.

Reliability

  • Recover interrupted Space invitations and member removals more reliably, with clearer reconnect actions.
  • Keep your conversation position and open thread stable as background updates arrive.
  • Stay responsive during startup and Slack catch-up, with fewer false approval failures and cleaner saved answers.
