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

  • View interactive HTML artifacts inside threads and save copies to Spheres.
  • Manage ToDos, FYIs, and Fun in one Feed, with a Done list and reopening controls.
  • Choose Queue or Steer when sending a message during an active run.

Desktop

  • Find Spheres with a searchable switcher and personalize private Spheres with colors and animated backgrounds.
  • Navigate channels, threads, and direct messages with clearer labels and more consistent focus.
  • See meaningful agent progress in a steadier timeline and review workflow run history.

Shared Spheres

  • Start shared threads immediately while sharing continues in the background.
  • Invite people by email, see clearer invitation status, and recover interrupted setup.
  • Get replies when mentioning the Sphere agent in a channel.
  • Paste or drop shared attachments with clearer upload progress and retry options.

Reliability

  • Keep drafts, private attachments, and chat history through refreshes, backup sync, and restarts more reliably.
  • See more accurate message delivery status, with fewer duplicate sends and clearer recovery steps.
  • Recover shared Sphere access more reliably across computers and membership changes.
  • Reduce background sync overhead and recover interrupted update downloads.
