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 Space conversations, invite participants, and use message reactions, replies, and agent mentions.
  • Dictate prompts in Orbit and Space conversations with recording controls and setup guidance.
  • Use Auto model selection with routing preferences and provider usage limits.

Desktop

  • Search Space conversations, jump to the latest messages, and keep your reading position as conversations update.
  • Switch computers within existing threads and see Git branch and line changes in coding conversations.
  • Manage alerts with a notification inbox, dismissal, and granular preferences.
  • Edit or delete routines from the thread drawer and configure webhook triggers.

Reliability

  • Keep Space read state and encrypted notification preferences in sync across devices.
  • Preserve thread deletions and newer local changes during sync, with better recovery after interruptions.
  • Improve image attachment previews during active conversations and recover stale Claude sessions.
