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 threads from Home, with easier channel creation and guest invitations.
  • Browse beside your conversation, open multiple tabs, and share annotated pages with your agent.
  • Let Auto choose among eligible AI models, with provider preferences and usage controls.

Desktop

  • Queue follow-up messages or steer an active chat turn.
  • Dictate prompts with clearer microphone permission guidance and recording feedback.
  • Search Space conversations, rename threads, and keep your reading position as messages arrive.
  • Choose Ollama or Apple Intelligence during onboarding, where available.

Companion Sync

  • Receive paired conversation messages and progress updates faster.
  • Run independent companion threads concurrently without waiting for one thread to finish.
  • Pair devices with persistent codes and clearer connection status.

Reliability

  • Recover more reliably from interrupted Space invitations, reconnects, and member removals.
  • Preserve newer local edits and conflict drafts during synchronization.
  • Restore saved task models after restart and keep the open conversation selected when other threads update.
  • Stay responsive while conversation history loads and Slack catches up.
