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 Neue and Thinkling agent avatars with custom colors, live activity, and reactions.
  • Get started through a persistent Welcome conversation with guided provider setup.
  • Preview scoped Sphere delegations before handing work to another agent.

Desktop

  • Find Spheres, agents, and chats in the new Home view, with a separate rail for shared Spheres.
  • Keep Sphere tree branches expanded as you navigate.
  • See progress while creating Spheres, saving artifacts, and confirming sharing.

Companion Sync

  • See shared participant activity and agent reactions in desktop conversations.
  • Keep completed responses and message order intact across device sync.
  • Recover queued work more reliably after going offline or restarting.

Reliability

  • Keep macOS Slack and Discord listeners available in the background, with improved Slack catch-up and broadcast reply capture.
  • Recover oversized Sphere history and see fewer unnecessary collaboration conflict notices.
  • Remove Spheres without endless refresh blockers, with clearer content choices and failure messages.
  • Benefit from more resilient sign-in, cloud settings recovery, and automatic update progress.
