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, expand them, and save copies to a Sphere.
  • Choose Queue or Steer when sending during an agent run, and restore queued messages to their original thread for editing.

Shared Spheres

  • Browse Threads and Channels in shared Spheres, with a General channel for shared conversations.
  • Start contextual one-to-one direct messages with Sphere members, including as a read-only member.
  • See invitations and clearer conversation audiences, leave shared Spheres, and access owned shared Spheres across your computers.

Desktop

  • Personalize Spheres with colors and animated backgrounds, and adjust the desktop palette.
  • Switch Spheres with a searchable picker and find recent threads in the sidebar.
  • Follow steadier run timelines that highlight meaningful work and fold background steps into Thinking.
  • Browse integrations by app and preview Brain images and supported local videos.

Reliability

  • Reduce memory use and interruptions while saving, syncing, and streaming shared conversations.
  • Get clearer paused-sync and delivery failure messages, with improved recovery for shared Sphere access.
  • Run scheduled workflows on demand, retain their scheduled time, and review workflow run history.
  • Recover more reliably from interrupted update downloads and failed installation attempts.
