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

  • Work together in live workspaces with private conversations and saved chat history.
  • Invite people into Spaces and create conversations for people only.
  • Use @mentions to hand work to an agent, with clearer attribution of agent responses.

Desktop

  • Get started with a shorter setup flow and clearer explanations of system permission requests.
  • Click your Chief of Staff's avatar to change its name or appearance.
  • Choose an approval mode when your agent first needs to take a consequential action.
  • Keep your saved composer model selected as provider catalogs load.

Reliability

  • Sync better preserves newer local Sphere edits and refreshes open windows when changes arrive.
  • Space invitations and setup recover more reliably after interruptions.
  • Long-running agent work can continue beyond thirty minutes.
  • Slack replies stay in their threads, and dropping folders into chat no longer triggers a folder-read error.
