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 shared Space conversations, invite people, and respond with reactions and replies.
  • Find messages with Spaces search and jump to the latest conversation updates.
  • Dictate prompts with recording controls, clearer feedback, and guided setup.
  • Use Auto to select models across desktop and cloud runs, with provider preferences and usage limits.

Desktop

  • Manage alerts with a notification inbox and granular notification preferences.
  • Set up private app integrations through guided agent conversations with explicit approval before publishing.
  • Switch computers within existing threads and edit or delete routines from the thread drawer.

Companion Sync

  • Keep Space read state and notification preferences in sync across devices.
  • Discover newly shared Spaces without restarting and recover messages after interrupted syncing.
  • Preserve thread deletions and resume partially completed invitations without resending successful ones.

Reliability

  • Enjoy smoother typing and keep your reading position as conversations update.
  • Keep unsaved provider and device settings while cloud details refresh.
  • Open ThinkOS links in the installed app and recover more reliably after signing out.
