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

  • Browse alongside each conversation with multiple tabs, a resizable panel, and a separate window option.
  • Mark up web pages and bring annotated screenshots into your conversation.
  • Collaborate in Spaces with invitations, replies, reactions, conversation search, and read state synced across devices.
  • Use Auto to choose models for your requests, with provider preferences and usage limits.

Desktop

  • Dictate prompts with recording controls and clearer setup guidance.
  • Rename conversations, jump to the latest messages, and keep your reading position as replies arrive.
  • Manage notifications in an inbox and choose whether macOS alerts appear while ThinkOS is focused.

Companion Sync

  • Pair devices with persistent manual codes, easier copying, and clearer connection status.
  • Paired conversations respond faster and recover message delivery more reliably after interruptions.
  • Space member names, photos, and device identity stay consistent through reconnects.

Reliability

  • Space messages show clearer pending status and recover more reliably when connections return.
  • Unsaved settings, thread deletions, and concurrent edits are better preserved during sync.
  • Conversations load sooner, typing stays more responsive, and completed threads no longer retain stale running indicators.
