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 with your agent.
  • Queue follow-up messages or steer an active chat turn, with clearer live tool activity.

Desktop

  • Choose automatic model routing, with Ollama and Apple Intelligence available during onboarding.
  • Create local Spheres from the New menu and rename agents and threads inline.
  • Dictate prompts with clearer recording controls and improved microphone permission handling.
  • Manage notifications through an inbox and granular preferences.

Companion Sync

  • Paired conversations deliver messages and activity updates faster and recover more reliably from interruptions.
  • Desktop pairing offers persistent manual codes, steadier controls, and clearer connection status.

Reliability

  • Keep your open conversation and scroll position steady as other threads update.
  • Restore saved task models after restart and keep progress commentary out of saved answers.
  • Recover Space invitations and reconnects more reliably while preserving local edits and conflict drafts.
  • Stay responsive during startup and Slack catch-up, with explicit confirmation before removing a Sphere.
