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

  • Use live workspaces and private conversations with saved chat history.
  • Invite people to Spaces and create conversations just for humans.
  • Hand off work to agents with @mentions.

Desktop

  • Get started with a shorter setup flow and clearer permission requests.
  • Click your Chief of Staff's avatar to change its name or appearance.
  • Your saved composer model stays selected as available models load.
  • Choose an approval mode when your agent reaches its first consequential action.

Reliability

  • Sync better preserves newer local Sphere edits and refreshes open windows when changes arrive.
  • Space invitations and conversation setup recover more reliably after interruptions.
  • Long-running agent tasks can continue beyond thirty minutes.
  • Dropping a folder into Workbench chat no longer triggers a file-reading error.
  • Slack replies stay in their original threads.
