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 and manage Spaces with conversations, participants, invitations, replies, reactions, search, and agent handoffs.
  • Use Auto routing to choose an available model based on the task, provider preferences, and usage limits.
  • Set up private app integrations conversationally from Spaces with clear approval prompts before publishing.

Desktop

  • Dictate prompts in desktop conversations with active controls, setup guidance, and clearer feedback.
  • Manage notifications, provider usage limits, webhook routines, account emails, cloud computers, and feature access from Settings.
  • Keep your place in long conversations with preserved scroll position and a jump-to-latest control.
  • Open thinkos:// links in the installed app and switch machines within existing conversations.

Companion Sync

  • Newly shared Spaces can appear on running devices and reconnect without restarting.
  • Messages, invitations, read state, settings, deletions, and device actions sync more reliably across desktop and companion devices.
  • Saved device connections and local Settings drafts remain visible while cloud details refresh.

Reliability

  • Interrupted or stale agent sessions recover more cleanly, while long-running provider turns can continue without a fixed 30-minute cutoff.
  • Space delivery, pending invitations, image attachments, notification preferences, and concurrent settings changes are more resilient.
  • Slack replies retain their thread context, and Discord reporters can receive completion updates when fixes ship.
