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

  • View HTML artifacts directly in conversations, expand them, and see the latest revision.
  • Saved artifacts retain their styling, with clearer access to Sphere copies and warnings when already saved.
  • See the agent's enforced work scope, with recalled context restricted to authorized sources.

Desktop

  • Shared sidebar channels open in chat more reliably, while Home sidebar conversations remain available.
  • New conversations preserve Sphere names and channel identity as you navigate.
  • Only shared Spheres receive sharing labels, and channel owners can delete shared channels.
  • Thinking status is more consistent, and the jump-to-latest control stays above the composer.

Companion Sync

  • Manual sync reports failures instead of waiting indefinitely.
  • Cancellation is preserved more reliably through Companion request handling and delivery.

Reliability

  • Space message delivery status remains available across restarts and matches the correct message.
  • Shared-channel reopening and invitation delivery recover more reliably.
  • Slack reconnection recovery avoids repeated rapid retries when failures persist.
