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

  • Choose Thinkling or Neue agent avatars, with reactions and animations that reflect agent activity.
  • Get started through a persistent Welcome conversation with guided provider setup.

Desktop

  • Browse Spheres, agents, and chats from the new Home view and dedicated Shared Sphere rail.
  • Mention Sphere Agents in Chief Think Agent threads and preview scoped delegations.
  • See clearer progress while creating Spheres, saving artifacts, and confirming sharing.

Companion Sync

  • Keep completed responses and message order more consistent across synced devices.
  • See shared participant activity in text threads.
  • Recover queued messages and collaboration work more reliably after offline restarts.

Reliability

  • Keep Slack and Discord listeners available in the background on macOS, with improved Slack catch-up and broadcast reply capture.
  • Recover large Sphere histories more safely and avoid stuck Sphere removal.
  • Experience fewer avatar crashes, stale activity indicators, and interruptions during sign-in.
  • See automatic update progress refresh more reliably.
