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 and expand HTML artifacts directly in conversations, with the latest revision shown automatically.
  • Save artifacts to Spheres and sync their encrypted app data.
  • Find Spheres with a searchable sidebar switcher and a pinned Create Sphere action.

Desktop

  • Place attachments inline with your message and remove them by deleting their tokens.
  • Manage integrations by service and edit Sphere settings in place.
  • Read clearer notifications, menus, attachment labels, and inline agent progress.
  • Send feedback from a panel while keeping your current workspace open.

Sharing and Sync

  • Share child Spheres in place while preserving their position under the parent.
  • See clearer distinctions between Sphere sharing, conversation audiences, pending access, and paused sharing.
  • Edit collaboration display names with more consistent updates across desktops.
  • Approve owner device trust with improved recovery and clearer refresh failures.

Reliability

  • Recover queued messages and delivery outcomes more reliably after interruptions.
  • Keep drafts, conversation history, and shared Sphere navigation more consistent during sync and account changes.
  • Receive clearer Companion sync failures and more reliable cancellation and queued prompt handling.
  • Recover update retries more reliably across relaunches and interrupted installs.
