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 HTML artifacts directly in conversations, expand them, and save copies to a Sphere.
  • Artifact app data is encrypted and syncs with its Sphere, with updates reflected immediately on desktop.
  • Follow the complete active progress trail, with clearer tool activity and recorded durations.

Desktop

  • Edit Sphere settings inline, with sharing actions separate from sync controls.
  • Browse a cleaner notifications popover that stays open while scrolling and offers a clear Dismiss all action.
  • See the agent's work scope and enjoy clearer conversation spacing and more consistent cards, dialogs, and menus.

Companion Sync

  • Queued prompts can be promoted into active work more reliably while preserving their intended conversation and context.
  • Companion delivery better preserves cancellations, completed outcomes, and errors across reconnects.
  • Manual sync failures are reported more clearly.

Reliability

  • Sphere navigation resumes after startup readiness, and shared sidebar channels open more reliably.
  • Space drafts stay tied to their session, and message delivery status better survives sync conflicts.
  • Shared Sphere recovery better preserves newer state, private channels, and backups.
  • Slack and Telegram recovery handles repeated connection failures more reliably.
