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 animated Neue or Thinkling agent avatars, customize colors and Thinkling shapes, and see reactions as agents work.
  • Get started through conversational provider setup in a persistent Welcome thread.
  • Find Spheres, agents, and chats in the new Home view, with a dedicated rail for shared Spheres.

Desktop

  • Mention Sphere Agents in Chief Think Agent threads and preview scoped delegations.
  • See participant activity in shared text threads with clearer unread indicators.
  • Share Spheres with clearer history consent, visible progress, and retryable errors.
  • Choose how to handle content when deleting a Sphere, with more reliable removal of its channels and shared copies.

Companion Sync

  • Keep completed responses and message order more consistent across paired devices.
  • Sync agent reactions across clients and keep the Chief's identity consistent in companion replies.
  • Connect paired companions more reliably when device clocks differ.

Reliability

  • Keep Slack and Discord listeners available while ThinkOS runs in the background.
  • Recover queued messages and channel work more reliably after offline restarts, including Slack broadcast replies.
  • Recover large Sphere histories more safely and reduce repetitive collaboration conflict notices.
  • Improve sign-in recovery, automatic update progress, and stability with animated avatars.
