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.

Paste or drop files directly into the desktop composer, with attachment titles that preserve the original filename.
Start conversations from Orbit with real file attachments.

Browse sub-sphere conversations in a flattened, navigable Spheres list.
Enjoy a cleaner Orbit landing experience with streamlined prompts and consistent sphere labels.
Integration-generated thread titles no longer expose hidden formatting markers.

Thread and sphere changes merge more safely across peers, reducing lost updates and accidental reappearance of deleted threads.
In-progress and newly created threads remain visible while synchronization and sidebar selection update.

Sphere updates now save consistently.
Large desktop actions and protected commands are handled more safely and predictably.
