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 respond with reactions, replies, and agent mentions.
  • Use Auto to select models for desktop and cloud work, with provider preferences and usage limits.
  • Dictate prompts in Orbit and Space conversations with recording controls and clearer setup guidance.

Desktop

  • Search Space conversations and jump to the latest messages while keeping your reading position as updates arrive.
  • Review and dismiss notifications in a desktop inbox, with finer control over which alerts you receive.
  • Switch computers within existing threads and edit or delete routines from the thread drawer.

Reliability

  • Keep Space read status and notification preferences in sync across devices.
  • More reliably preserve thread deletions and changes made while sync is running.
  • Keep Slack agent replies focused on the originating thread.
  • Improve image attachment previews and recovery from stale Claude sessions.
