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

  • Create Spaces conversations, invite participants, and use message reactions and replies.
  • Dictate prompts in Orbit and Spaces with recording controls and clearer setup guidance.
  • Use Auto to choose models across desktop and cloud runs, with provider preferences and usage limits.

Desktop

  • Search Spaces conversations and jump to the latest messages while preserving your reading position.
  • Switch machines within existing threads and see coding changes directly in the conversation.
  • Edit or delete routines from the thread drawer and configure webhook triggers.
  • Manage alerts with a notification inbox, dismissal, and granular preferences.

Companion Sync

  • Keep Space read status and encrypted notification preferences in sync across devices.
  • More reliably retain local edits and recover interrupted sync sessions.

Reliability

  • Image attachments and previews remain available more reliably during active conversations.
  • Recover stale Claude sessions and resume interrupted cloud Brain setup.
  • Keep incomplete conversations out of Spaces navigation and preserve unsaved provider settings.
