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 with Everything, Todos, FYIs, and Fun filters, including agent-created ToDo threads.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to Spheres.
  • Follow agent work in a collapsible run timeline with saved steps and clearer failure details.
  • Run scheduled workflows on demand while keeping their scheduled time of day.

Desktop

  • Find Spheres with a searchable switcher and reopen conversations from Recent and No Sphere sections.
  • Place attachments inline with your message and remove them by deleting their tokens.
  • See the selected conversation audience; new shared-Sphere conversations start with everyone by default.
  • Create local Spheres during first-run setup before configuring AI.

Sharing and Sync

  • Share child Spheres in place and see clearer distinctions between sharing, sync, and conversation access.
  • Edit your collaboration display name with more reliable synchronization across devices.
  • Recover shared-Sphere access and owner device trust with clearer approval and recovery controls.

Reliability

  • Reduced idle memory use and fixed a crash loop when reading saved data.
  • Improved queued-message delivery, cancellation, and saved-answer recovery.
  • Improved recovery of shared conversations, private backups, and conflicting updates.
  • Made installer retries more reliable across relaunches.
