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

  • Browse alongside each conversation with multiple tabs, a separate window option, and page annotations you can send into chat.
  • Create Space conversations, invite participants, and use replies, reactions, and conversation search.
  • Use Auto model selection with provider preferences and usage limits.

Desktop

  • Dictate prompts, rename conversations, and switch computers within existing threads.
  • Keep your reading position as conversations update, with a shortcut to jump to the latest messages.
  • Manage notifications in an inbox and choose whether macOS alerts appear while ThinkOS is focused.

Companion Sync

  • Pair devices with persistent codes, copy controls, and clearer connection status.
  • Keep Space read state, participant names, and photos consistent across devices.
  • Recover interrupted invitations and discover newly shared Spaces without restarting.

Reliability

  • Space posts are saved locally while offline, with a clear pending delivery state.
  • Conversations no longer remain marked as running after work has stopped.
  • Attach files faster and retain image previews more reliably during active conversations.
  • Slack replies preserve thread context and follow through on promised work before sending a final response.
