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 reopen their latest revisions.
  • Choose Queue or Steer when sending a message during an active run.
  • Manage ToDos, FYIs, and Fun items in one Feed, with a Done list for completed ToDos.

Desktop

  • Find Spheres with a searchable switcher and distinguish channels, threads, and direct messages in the sidebar.
  • Start threads in the current Sphere, with more consistent navigation and composer focus.
  • Paste or drop shared attachments, see upload progress, and recover failed uploads.
  • See clearer agent progress, meaningful run steps, and actionable failure messages.

Reliability

  • Keep shared drafts through refreshes and recover stalled Sphere creation.
  • Retry unconfirmed messages without duplicating saved posts or marking them as failed.
  • Recover invitations after signup and restore shared Sphere access across your computers.
  • Preserve private chat history and attachments across backup sync.
  • Reduce background sync overhead and recover more reliably from interrupted update downloads.
