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, replies, reactions, and conversation search.
  • Browse beside each conversation, open multiple tabs, and share annotated pages with your agent.
  • Queue follow-up messages or steer an active chat turn.
  • Use Auto model selection, with Ollama and Apple Intelligence available as onboarding options.

Desktop

  • Find Space search in the sidebar and access Space and channel actions with right-click menus.
  • Rename agents inline and give threads your own titles.
  • Dictate prompts with clearer recording feedback and improved microphone permission handling.
  • Keep your reading position as conversations update, with a shortcut to jump to the latest messages.

Companion Sync

  • Pair devices with clearer connection status, persistent manual codes, and more reliable recovery.
  • Keep Space read state in sync across devices.
  • Recover shared messages and interrupted invitations more reliably after reconnecting.

Reliability

  • Keep ThinkOS more responsive during startup and Slack history catch-up.
  • Restore each task's saved model after restarting.
  • Preserve conflict drafts and newer local edits during Space sync.
  • Require exact confirmation before removing a Sphere.
