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

  • Create shared Spaces, invite people, and use replies, reactions, and conversation search.
  • Browse beside conversations with multiple tabs, page annotations, and a separate browser window.
  • Use Auto model selection and find Ollama and Apple Intelligence options during setup.

Desktop

  • Find Search in Space in the sidebar and right-click Spaces and channels for quick actions.
  • Rename threads manually and rename agents by clicking their profile names.
  • Keep your reading position as conversations update, with a shortcut to jump to the latest messages.
  • Dictate prompts with clearer recording controls and improved microphone permission handling.

Companion Sync

  • Pair devices with persistent codes, copy controls, and clearer connection status.
  • Keep pairing controls stable during background checks and retain a new code after the first phone connects.
  • Keep Space read state in sync across devices.

Reliability

  • Space messages appear immediately with a clear pending state while delivery completes.
  • Recover more reliably from interrupted Space sync and invitations while preserving local edits and conflict drafts.
  • Stay responsive during startup and Slack catch-up, with better recovery from Slack rate limits.
  • See current tool activity without losing the response text already shown.
