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 beside each conversation with multiple tabs, a resizable panel, and a separate window option.
  • Mark up web pages and share annotated screenshots directly in conversations.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and read state shared across devices.
  • Use Auto to select models for your requests, with provider preferences and usage limits.

Desktop

  • Dictate prompts in Orbit and Space conversations with recording controls and clearer setup guidance.
  • Rename conversations and switch computers within existing threads.
  • Manage alerts through a notification inbox and granular preferences, including macOS notifications while ThinkOS is focused.
  • Edit or delete routines from the conversation drawer.

Companion Sync

  • Pair companions with persistent codes, copy controls, and more accurate connection status.
  • Keep a fresh pairing code visible after the first phone connects so another device can join.

Reliability

  • Space sends are saved locally with clear pending status, including support for accepting posts while offline.
  • Shared Spaces and interrupted invitations recover more reliably after connection problems.
  • Conversations better preserve your reading position as messages arrive, with a shortcut to jump to the latest.
  • Faster initial loading and attachment handling help keep conversations responsive.
