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

  • Personalize agents with animated Neues, Thinkling avatars, and custom colors, with reactions that reflect their activity.
  • Get started through a persistent Welcome conversation with guided provider setup.

Desktop

  • Find Spheres, agents, and chats in the new Home view, with a dedicated rail for shared Spheres.
  • Preview scoped Sphere delegations and mention Sphere Agents in Chief Think Agent threads.
  • See clearer sharing progress, retry failures in place, and choose what happens to content when deleting a Sphere.

Companion Sync

  • Keep completed responses and message order consistent across connected devices.
  • See shared participant activity and agent reactions in desktop conversations.
  • Keep queued messages available through interruptions and recovery.

Reliability

  • Keep Slack and Discord listeners available while ThinkOS runs in the background, with more reliable Slack catch-up after offline restarts.
  • Recover oversized Sphere history and reduce repetitive collaboration conflict notices.
  • Improve sign-in recovery, live avatar stability, and automatic update progress.
