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

  • Find ToDos, FYIs, and Fun in one Feed, with filters for each.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to Spheres.
  • Follow agent work in a collapsible timeline with tool activity and saved progress.

Desktop

  • Find Spheres faster with a searchable switcher and Recent threads.
  • Place attachments inline with your message text.
  • Run scheduled workflows on demand without changing their scheduled time, and review their run history.
  • Agent runs use more relevant context sources within their permitted Sphere scope.

Sharing

  • See the current conversation audience and change it from one menu.
  • Send invitations without waiting for the People dialog to finish, and leave shared Spheres from desktop.
  • Share child Spheres in place and review which nested Spheres a delete-everywhere action will remove.
  • Shared Sphere agents honor channel reply settings and explain when replies need setup.

Reliability

  • Sphere sync status more clearly reports pending setup, failures, and recovery.
  • Improved message recovery preserves queued sends, drafts, and delivery errors.
  • Reduced idle memory use helps prevent crash loops, and Slack listeners recover more reliably after interruptions.
  • Improved installer recovery preserves update retries across relaunches.
