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

  • Browse ToDos, FYIs, and Fun in one Feed, with a Done list and controls to reopen or remove ToDos.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to a Sphere.
  • Choose Queue or Steer when sending a message during an active run.

Shared Spheres

  • Find Threads and Channels together and start private direct messages with Sphere members, including read-only members.
  • See clearer audience labels that distinguish private conversations from messages shared with everyone.
  • Share child Spheres in place, choose whether to include conversation history, and leave shared Spheres from desktop.

Desktop

  • Find Spheres with a searchable sidebar switcher and personalize them with colors and animated backgrounds.
  • Keep attachments inline with your draft and preview Brain images and local videos.
  • Follow a steadier run timeline that keeps meaningful work visible and folds background steps into Thinking.
  • Review workflow run history and run scheduled workflows on demand while preserving their scheduled time.

Reliability

  • Recover shared Sphere access and invitations more reliably across your computers.
  • See clearer sharing and sync status, with recovery actions when sharing pauses.
  • Benefit from lower memory use and more reliable saving during busy conversations and background syncing.
  • Retry interrupted update downloads and recover failed installation attempts across relaunches.
