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

  • Browse one Feed for ToDos, FYIs, and Fun, with a Done list and controls to reopen or remove ToDos.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to a Sphere.
  • Choose Queue or Steer when sending a message during an active run.

Desktop

  • Find Spheres faster with a searchable switcher, Recent threads, and clearer Threads and Channels sections.
  • See conversation audiences and private thread labels more clearly, and start contextual direct messages with shared Sphere members.
  • Personalize Spheres with colors and animated backgrounds, and preview Brain images and local videos.
  • Follow steadier run timelines that emphasize meaningful work, and review workflow run history.

Reliability

  • Shared Spheres appear more reliably across your computers, with improved invitation recovery and rejoining that preserves earlier posts.
  • Sync and delivery statuses better explain paused sharing, failed sends, and available recovery actions.
  • Reduced memory use and improved saving help keep the app responsive during background sync.
  • Update indicators are easier to find, and interrupted downloads and failed installs recover more reliably.
