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

  • Find ToDos, FYIs, and Fun in one Feed, with controls to complete, reopen, or remove ToDos and browse a Done list.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to a Sphere.
  • Follow steadier agent run timelines that show meaningful steps and fold background work into Thinking.

Desktop

  • Find Spheres faster with a searchable sidebar switcher and Recent threads.
  • Personalize Spheres with colors and animated backgrounds, and adjust the desktop palette.
  • Place attachments inline with your message and preview Brain images and local videos.
  • Review workflow run history and run scheduled workflows on demand while preserving their scheduled time.

Shared Spheres

  • See a clearer conversation audience and switch who receives your message from one menu.
  • Start contextual direct messages with Sphere members, including members with read-only access.
  • See incoming invitations, create channels from the shared sidebar, and leave shared Spheres.
  • Open shared Spheres across your computers with improved access recovery and clearer sharing status.

Reliability

  • Reduce memory use and improve responsiveness during background sync and saves.
  • Keep the app open when a Sphere sync worker runs out of memory, with a clearer paused-sync explanation.
  • Recover more reliably from interrupted message delivery, shared Sphere setup, and Slack connection failures.
  • See desktop update availability again, with improved install failure reporting and retry recovery.
