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

  • Navigate nested Spheres and threads from Home, create channels, and invite guests within Spheres.
  • Browse beside your conversation, open multiple tabs, and share annotated pages with your agent.
  • Queue follow-up messages or steer an active chat turn.

Desktop

  • Search Space conversations, reply to messages, and add reactions.
  • Dictate prompts with recording controls and clearer microphone setup feedback.
  • Use automatic model routing and restore saved task model choices after restarting.
  • Manage notifications from an inbox with granular preferences.

Companion Sync

  • Receive paired thread messages and status updates faster and more reliably.
  • Run independent companion threads concurrently.
  • Pair devices with persistent codes, native copy controls, and clearer connection status.

Reliability

  • Recover interrupted Space invitations and reconnects more reliably.
  • Keep your conversation position and open thread stable as background updates arrive.
  • Stay responsive during Slack catch-up and workspace startup.
  • Review conflicting Space changes while preserving conflict drafts across refreshes.
