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

  • View interactive HTML artifacts inside conversations, see their latest revision, and save copies to a Sphere.
  • Find ToDos, FYIs, and Fun in one Feed, with agent-created ToDos linked to their source conversations.
  • Follow agent work in a steady timeline that keeps progress visible and collapses in place when finished.

Desktop

  • Find Spheres with a searchable switcher and reopen recent threads from the sidebar.
  • Place attachments inline with your message and adjust desktop colors from the theme menu.
  • Run scheduled workflows on demand, review run history, and preserve their scheduled time of day.

Shared Spheres

  • Create channels directly from the shared Sphere sidebar and see the current conversation audience in one menu.
  • Send invitations without blocking the People view, distinguish pending invitees from members, and leave shared Spheres.
  • Share child Spheres in place and receive clearer notices when sharing stops or an owner deletes a Sphere.

Reliability

  • Reduce memory use and improve responsiveness during idle syncing and shared conversation streaming.
  • See clearer sync and delivery failures, with better recovery for queued messages and interrupted setup.
  • Keep drafts and newer conversation state through sync recovery, and let silent Slack agents reconnect automatically.

Updating

  • The desktop update indicator is restored, with clearer failed-install messages and retry recovery across relaunches.
  • Packaged builds update from the configured beta channel.
  • Download the latest macOS installer
