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

  • Each sphere now opens its own scoped Orbit landing, giving you a clear starting point without automatically resuming a thread.
  • ThinkOS now reopens to your last active section and sphere, while preserving expanded and collapsed sidebar groups across restarts.
  • Thread rows now show working, settled, and needs-review statuses at a glance.

Desktop

  • The sidebar has tighter spacing, clearer hover actions, helpful tooltips, and pinned composer, search, and settings controls.
  • Orbit’s density control now lives in the persistent breadcrumb bar and stays out of the way once a thread is open.
  • Command-click a sphere chevron to expand or collapse the full accordion, and use arrow keys for faster sidebar navigation.
  • Keyboard shortcuts now stay scoped to the active surface, while menus and selectors keep keyboard focus contained.

Reliability

  • Archived threads are no longer considered when ThinkOS determines where to resume work.
  • First-run Orbit guidance now appears in the right sequence, with improved layout and corrected display-density styling.
