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.
  • Save artifacts to a Sphere with their styling preserved and a warning when an artifact is already saved.

Desktop

  • Reopen shared channels at the correct conversation.
  • Reach the latest messages with a jump control positioned above the composer.
  • See cleaner typing activity without your own typing echoed back.
  • Enjoy smoother Welcome transitions and preserved onboarding transcripts.

Companion Sync

  • Manual sync reports failures instead of waiting indefinitely on an unresponsive connection.
  • Cancellation is preserved as Companion requests are accepted and delivered.

Reliability

  • Recall respects authorized context while retaining current attachments and connector sources.
  • Conversation context includes authorized private content from descendant Spheres.
  • Shared Sphere sync and Slack recovery handle repeated failures with more measured retries.
  • Vault backups are preserved when replacement fails.
