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 Neues avatars, custom colors, or uploaded images, with larger avatars in chats.
  • Get started through a persistent Welcome conversation with provider setup and secure setup links.
  • Browse Spheres, Agents, and Chats from the new Home view while keeping Home selected as you open threads.

Desktop

  • Find shared Spheres in a dedicated rail and collaboration Spheres in settings.
  • See clearer sharing previews, history consent, progress, and retry options.
  • 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 intact across device sync.
  • See participant activity in shared text threads.
  • Keep queued messages through interruptions and recover saved collaboration work after offline restarts.

Reliability

  • Recover more reliably from brief sign-in failures and cloud service outages.
  • Resume saved Slack work with more consistent ordering and fewer repeated actions.
  • See automatic update progress refresh correctly.
