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

  • Resume ongoing work from Home, with Spheres, agents, chats, and session history easier to find.
  • Get started through a persistent Welcome conversation with provider recommendations and improved setup recovery.
  • Personalize agents with animated Neue and Thinkling avatars, custom colors, and Thinkling shapes.

Desktop

  • Navigate top-level and nested Spheres more easily, and open a Sphere's agent from its sidebar.
  • Share Spheres with clearer readiness guidance, invitation flows, progress, and retry messages.
  • See participant activity in shared threads without seeing your own typing indicator.
  • Receive compact notifications that stay visible through native gestures and dialogs.

Reliability

  • Reduce background disk activity during collaboration sync, especially with large shared documents.
  • Recover queued messages and channel work more reliably after offline restarts or stalled delivery.
  • Keep Slack and Discord listeners available in the background on macOS.
  • Connect Google accounts with more reliable account and permission verification.
  • See automatic update progress refresh more reliably.

Companion Sync

  • Preserve completed responses and message order across device sync while keeping partial responses local.
  • Improve initial pairing sync reliability when device clocks differ.
