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 shared across devices.
  • Browse beside your conversation with multiple tabs, a separate window option, and page annotations you can send to your agent.
  • Use automatic model selection, queue follow-up messages, or steer an active chat turn.

Desktop

  • Create local Spheres from the New menu and get inline Sphere setup help from your Chief of Staff.
  • Choose Ollama or Apple Intelligence during setup, with clearer checks before local setup reports success.
  • Dictate prompts with improved microphone permissions and recording feedback.
  • Keep your open conversation and scroll position as other threads update, and rename agents directly from their profiles.

Reliability

  • Recover more reliably from interrupted Space sync and invitations while preserving newer edits and conflict drafts.
  • Restore saved task models after restart and keep progress commentary out of saved answers.
  • Stay responsive during Slack catch-up and startup, with fewer false approval failures.
  • Pair companion devices with steadier desktop controls, persistent pairing codes, and clearer connection status.
