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 and save copies to a Sphere.
  • Personalize Sphere colors and animated backgrounds, and adjust the desktop palette.

Desktop

  • Switch Spheres with searchable flat pickers and reopen recent threads more easily.
  • Keep attachments inline with your message and follow agent work in a steady, collapsible timeline.
  • Review workflow run history, run workflows on demand, and preserve their scheduled time of day.

Shared Spheres

  • See incoming invitations and start contextual 1:1 direct messages with fellow members, including from read-only membership.
  • Choose a conversation audience from one clear control, with shared conversations starting with Everyone by default.
  • Create channels from the shared sidebar, leave shared Spheres, and see clearer explanations when sharing pauses or stops.

Reliability

  • Get clearer sync and delivery status, with better recovery for failed sends and shared Sphere setup.
  • Keep drafts and conversations more dependable across navigation, account changes, and sync recovery.
  • Reduce background memory use and improve recovery when Slack agents stop responding.

Updating

  • Packaged builds update from the configured beta channel.
  • The desktop update indicator is restored, with clearer installation failures and retry handling.
