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 people, and respond with reactions and replies.
  • Find messages with Spaces search and keep read status synced across devices.
  • Use Auto model selection with provider preferences and usage limits.

Desktop

  • Dictate prompts in Orbit and Space conversations with recording controls and setup guidance.
  • Manage alerts through a notification inbox and granular notification preferences.
  • Switch computers in existing threads and edit or delete routines from the thread drawer.
  • Set up app integrations through private, agent-guided conversations with explicit approval before publishing.

Companion Sync

  • Pair companions with clearer manual instructions, persistent pairing codes, and native copy controls.
  • See more accurate connection status while background checks preserve your device settings drafts.
  • Discover newly shared Spaces without restarting and resume partial invitations without resending successful ones.

Reliability

  • Keep your reading position as conversations update, with a shortcut to jump to the latest messages.
  • Enjoy smoother typing and more reliable image attachment previews.
  • Recover shared messages after sync interruptions while preserving thread deletions and newer local edits.
  • Open ThinkOS links in the installed app and follow clearer update progress in Settings.
