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 a persistent Welcome conversation with guided provider setup.
  • Find Spheres, agents, and chats in the new Home view and access shared Spheres from a dedicated rail.

Desktop

  • Mention Sphere Agents in Chief Think Agent threads and preview scoped delegations.
  • See clearer sharing progress, retry failed confirmations, and review history-sharing consent.
  • Choose what content to keep when deleting a Sphere, with more reliable removal of shared copies.
  • See participant activity in shared text threads with fewer noisy status and conflict notices.

Companion Sync

  • Keep completed responses and message order consistent across synced devices.
  • Recover queued messages more reliably after interruptions, restarts, or stopping a run.
  • Connect and complete initial companion sync more reliably when device clocks differ.

Reliability

  • Receive agent approval prompts more reliably so work waiting for permission can continue.
  • Keep Slack and Discord listeners available in the macOS background and recover missed channel work after offline restarts.
  • Recover large Sphere histories more safely and avoid repeated processing during Slack catch-up.
  • Recover sign-in and cloud settings after brief service failures, and keep automatic update progress refreshed.
