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

  • Organize Feed with Todos, FYIs, and Fun, plus a Done list for completed todos.
  • View interactive HTML artifacts inside conversations and save them to a Sphere.
  • Choose Queue or Steer when sending a message during an active run.

Desktop

  • Find Spheres with a searchable switcher and clearer Channels, Threads, and direct-message lists.
  • Create channels and start threads with more consistent navigation and keyboard focus.
  • See clearer conversation audiences, invitation status, and sharing recovery options.

Shared Spheres

  • Paste or drop shared attachments, track uploads, and retry failed deliveries.
  • Get Sphere agent replies to channel mentions and replies to earlier messages.
  • Keep shared drafts through refreshes and recover failed conversation starts.

Reliability

  • Reduce memory use and improve responsiveness during background sync.
  • Preserve chat history and private attachments more reliably across backup and sync.
  • Avoid reporting saved messages as failed and reduce duplicate messages on retry.
  • Recover more reliably from interrupted update downloads and installation attempts.
