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 legacy Tasks moved into individual ToDo threads.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to a Sphere.
  • Follow agent work through a collapsible timeline with acknowledgements, tool activity, and saved progress.
  • Run scheduled workflows on demand while preserving their scheduled time, with results posted to Feed.

Desktop

  • Find Spheres faster with a searchable switcher, a pinned Create Sphere action, and Recent threads.
  • Place attachments directly within your message and remove them by deleting their tokens.
  • Get a calmer Welcome experience with preserved conversations and the option to create local Spheres without AI setup.
  • Browse integrations by service and send feedback without leaving your current context.

Shared Spheres

  • See the current conversation audience in one selector, with safeguards against sharing text drafted before choosing Everyone.
  • Get replies from the Sphere's own agent in shared threads, using approved sources and respecting its off switch.
  • Send invitations without locking the People panel and share child Spheres in place.
  • Review an owner-deleted Sphere before removing your local copy, which remains read-only.

Reliability

  • Recover shared Sphere setup, invitations, and paused sharing with clearer status and recovery guidance.
  • Keep drafts and delivery errors visible when sends fail, with stronger protection against duplicate sends.
  • Benefit from lower idle memory use and fixes for startup crash loops and stale conversation state.
  • Recover interrupted Slack connections and macOS updates more reliably.
