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 a Done list and controls to reopen or remove ToDos.
  • View interactive HTML artifacts inside conversations and save copies to Spheres.
  • Run scheduled workflows on demand and review their run history.

Desktop

  • Find Spheres with a searchable flat switcher and return to recent threads from the sidebar.
  • Personalize Spheres with colors and animated backgrounds, and adjust desktop palettes.
  • Place attachments inline in your draft and preview Brain images and supported local videos.
  • Follow agent progress in a steady timeline that collapses in place when work finishes.

Shared Spheres

  • Start contextual one-to-one messages with fellow Sphere members, including read-only members.
  • See incoming invitations, send invites without blocking People, and leave shared Spheres from settings.
  • See the current conversation audience clearly and change it from one menu.
  • Create channels from the shared sidebar and see which agent answers a thread.

Reliability

  • Get clearer sync, paused-sharing, and message delivery status with recovery options.
  • Recover shared conversations, invitations, and private channels more reliably after interruptions.
  • Experience lower background memory use and smoother shared-thread streaming.
  • See desktop update availability in the sidebar and retry failed installations more reliably.
