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 dedicated filters; legacy Tasks move into their own ToDo threads.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to a Sphere.
  • Follow agent work in a collapsible run timeline with saved steps and recorded durations.

Desktop

  • Switch Spheres with a searchable picker and find Recent threads and No Sphere conversations in the sidebar.
  • Place attachments inline with your message and remove them by deleting their tokens.
  • Create local Spheres during setup without configuring AI first.
  • Run scheduled workflows on demand while preserving their scheduled time of day.

Sharing

  • See the current conversation audience in one selector, with a menu to change it.
  • Failed Everyone conversation starts preserve your draft and audience choice and explain what happened.
  • Share child Spheres in place and see clearer distinctions between private access, pending membership, and paused sharing.
  • Edit your collaboration display name and recover owner access across devices with approval controls.

Reliability

  • Reduce idle memory use and prevent an out-of-memory crash loop.
  • Recover silent Slack agents automatically and provide clearer replies when requests fail.
  • Preserve newer conversations, drafts, and delivery outcomes more reliably during sync and recovery.
  • Improve update recovery across installation attempts and relaunches.
