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 a Done list and controls to reopen or remove ToDos.
  • View interactive HTML artifacts inside conversations, expand them, and save copies to a Sphere.
  • Run scheduled workflows on demand and review their run history.

Desktop

  • Find Spheres faster with searchable flat pickers and Recent threads.
  • Personalize Spheres with colors and animated backgrounds, and adjust the desktop palette.
  • Place attachments inline with your message and preview images and supported local videos in Brain.
  • Follow agent progress in a steadier timeline that collapses in place.

Shared Spheres

  • See incoming invitations, create channels from the sidebar, and start direct messages with fellow members.
  • Choose whether to create a Sphere agent and include existing thread history when sharing.
  • Access shared Spheres across your computers with improved owner-device recovery.
  • See clearer audience and sharing status, leave shared Spheres, and choose whether to remove an owner-deleted copy.

Reliability

  • Reduce memory use and save delays, with fixes for startup crash loops and competing saves.
  • Recover queued messages and shared conversations more reliably, with clearer delivery failures and retry options.
  • Keep agent context focused on relevant, authorized sources and improve verification of saved generated files.
  • See desktop update availability again, with more reliable installation retries across relaunches.
