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

  • Collaborate in Spaces with invitations, message reactions, replies, and conversation search.
  • Dictate prompts in Orbit and Spaces with recording controls and setup guidance.
  • Use Auto to select models across desktop and cloud runs, with provider preferences and usage limits.
  • Start private, agent-led integration setup from Spaces and approve publishing explicitly.

Desktop

  • Manage alerts in a notification inbox with granular notification controls.
  • Switch computers within existing threads and edit or delete routines from the thread drawer.
  • Add verified email addresses and combine accounts with consent from both accounts.

Companion Sync

  • Keep Space read state and encrypted notification preferences in sync across devices.
  • Discover newly shared Spaces without restarting, with better reconnection and preservation of thread deletions.
  • Keep unsaved Devices settings intact while cloud details refresh.

Reliability

  • Type more smoothly in long conversations and keep your reading position as messages arrive.
  • Resume partially completed Space invitations without resending successful invitations.
  • View image attachments more reliably during active conversations.
  • Open ThinkOS links in the installed app.
