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

  • The redesigned sidebar separates places from your activity stream, gives Pinned its own section, and groups threads by recency.
  • Reorder sidebar sections and adjust their heights to fit the way you work.
  • Everything now behaves as a clear all-context destination, while spheres focus on their own subtrees.

Desktop

  • ThinkOS now sizes its default window to your display for a better first launch.
  • Settings, onboarding, provider setup, and the startup experience use clearer, more consistent language and presentation.
  • The writing toolbar stays out of the way until you begin composing.

Companion Sync

  • Improved companion synchronization keeps conversations and response progress more consistent across connected experiences.
  • Workflow permission handling is clearer and more dependable when work requires approval.

Reliability

  • Long sphere lists now scroll cleanly without overlapping neighboring sidebar sections.
  • Sidebar selection, icon alignment, update notices, managed secrets, schedules, and memory capture behave more consistently.
