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

  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and read state that follows you across devices.
  • Browse beside your conversation with multiple tabs, a separate window option, and page annotations you can share with your agent.
  • Let Auto select models for your tasks, with provider preferences and usage limit controls.

Desktop

  • Dictate prompts with recording controls and clearer setup guidance.
  • Rename conversations, jump to the latest messages, and keep your reading position as replies arrive.
  • Manage alerts from a notification inbox and choose whether macOS notifications appear while ThinkOS is focused.

Companion Sync

  • Pair companions with persistent codes, copy controls, and clearer connection status.
  • Keep desktop pairing controls stable during background checks and continue pairing additional devices.
  • Receive paired conversation messages more reliably, with reduced delivery delays.

Reliability

  • Space messages appear immediately with pending delivery status, including when you are offline.
  • Recover more reliably from interrupted Space sync and invitations while preserving newer edits and thread deletions.
  • Review Space conflicts in a dedicated conversation and retain resolution drafts through refreshes.
  • Load the desktop sooner and keep typing more responsive in long conversations.
