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

  • Find ToDos, FYIs, and Fun in one Feed, with a Done list and controls to reopen or remove ToDos.
  • View interactive HTML artifacts inside conversations and save copies to a Sphere.
  • Follow steadier agent progress timelines that emphasize meaningful steps.

Desktop

  • Find Spheres with a searchable switcher and return to recent threads.
  • Personalize Spheres with colors and animated backgrounds.
  • Preview Brain images and local videos, and manage attachments inline in the composer.
  • Review workflow run history and run scheduled workflows on demand.

Sharing

  • Start direct messages with shared Sphere members, including members with read-only access.
  • See incoming Sphere invitations, create channels from the sidebar, and leave shared Spheres.
  • Choose whether to create a Sphere agent and include existing conversation history when sharing.
  • See clearer conversation audiences and recover shared Sphere access across your computers.

Reliability

  • Reduce memory use during saves and syncing, and keep Sphere sync memory failures from crashing the app.
  • Get clearer delivery failures, paused sharing explanations, and recovery options.
  • Recover more reliably from interrupted updates, with a restored desktop update indicator and improved retry controls.
