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

  • Browse alongside conversations with tabs, a separate window, and page annotations you can send to your agent.
  • Create Space conversations, invite participants, reply to messages, and add reactions.
  • Use Auto model selection with routing preferences and provider usage controls.

Desktop

  • Dictate prompts with clearer recording controls and setup guidance.
  • Search Space conversations, rename threads, and jump to the latest messages while preserving your reading position.
  • Manage notifications in an inbox and choose whether macOS alerts appear while ThinkOS is focused.

Companion Sync

  • Pair devices with persistent codes, native copy controls, and clearer connection status.
  • Keep pairing another device after the first connects, with more reliable paired conversation delivery.

Reliability

  • Space messages save locally with a visible pending state while awaiting delivery.
  • Recover more reliably from interrupted Space sync and invitations while preserving newer edits and thread deletions.
  • Review Space sync conflicts and retain resolution drafts across refreshes.
  • Load the desktop sooner and keep typing responsive in long conversations.
