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 conversations, save them to a Sphere, and share them in channels.
  • Find ToDos, FYIs, and Fun in one Feed, with controls to complete, reopen, or remove ToDos.
  • Choose Queue or Steer when sending a message during an active run.

Desktop

  • Find Spheres with a searchable switcher and navigate shared Threads and Channels from the sidebar.
  • See clearer conversation audiences and start contextual direct messages with shared Sphere members.
  • Personalize Spheres with colors and animated backgrounds, and preview Brain images and local videos.
  • Follow steadier run timelines that emphasize meaningful work, and review workflow run history.

Companion Sync

  • Discover and open shared Spheres more reliably across your computers, including devices added after you joined.
  • Recover invitations and rejoin shared Spheres more reliably while retaining earlier posts.
  • See clearer device approval requests, sharing status, and recovery actions.

Reliability

  • Reduce memory use and avoid app crashes when a Sphere sync worker runs out of memory.
  • Keep message delivery status accurate when sharing is paused or delivery fails.
  • Recover interrupted update downloads and retry failed installations more reliably.
  • Improve Slack recovery after disconnects and preserve drafts through conversation refreshes.
