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 conversations in Spaces, invite people, view participants, and post in human-only conversations.
  • Get started with a simpler AI setup and personalize your Chief of Staff by clicking its avatar.
  • Choose an approval mode at the first consequential action, with clearer explanations for system permission requests.

Desktop

  • Your saved composer model stays selected as provider catalogs load.
  • Agent work can continue beyond thirty minutes.
  • Simple Ollama greetings respond faster.
  • Dropping a folder into the Workbench composer no longer triggers a folder-read error.

Reliability

  • Sync better preserves newer local Sphere edits and changes made while synchronization is running.
  • Open windows refresh when background sync brings in changes.
  • Space invitations and setup recover more reliably after interruptions.
  • Slack replies stay in their original threads.
