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

  • Navigate nested Spheres and their threads from Home, with unassigned conversations listed separately.
  • Browse alongside conversations with multiple tabs, a separate window, and page annotations you can send into chat.
  • Queue follow-up messages or steer an active chat turn.

Desktop

  • Create Spheres and channels from the global New menu, and invite guests from within Spheres.
  • Search Space conversations, rename threads, and use message reactions and replies.
  • Choose automatic model routing and restore saved task models after restarting.
  • Dictate prompts with clearer microphone controls and permission feedback.

Companion Sync

  • Receive paired-thread messages and progress updates faster and more reliably.
  • Run independent companion threads concurrently.
  • Pair devices with persistent codes, native copy controls, and clearer connection status.

Reliability

  • Keep your open conversation and scroll position steady as background updates arrive.
  • Recover more reliably from interrupted Space invitations, reconnects, and member removals.
  • Keep ThinkOS responsive while Slack history and vault content load.
  • Require explicit confirmation before removing a Sphere.
