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

  • Personalize agents with Neues, Thinklings, and custom colors, with live activity animations and reactions.
  • Get started through a persistent Welcome conversation with guided provider setup.

Desktop

  • Browse Spheres, Agents, and Chats from the new Home view, with remembered Sphere branches.
  • Access shared Spheres from a dedicated rail.
  • Preview Sphere sharing and scoped agent delegations, with clearer consent, progress, and retry options.

Companion Sync

  • Keep completed replies and message order consistent across synced devices.
  • See shared participant activity and agent reactions in desktop conversations.
  • Preserve queued message delivery through interruptions and recovery.

Reliability

  • Keep macOS Slack and Discord listeners available in the background, with more reliable Slack catch-up after offline restarts.
  • Recover more smoothly from brief sign-in failures and cloud service outages.
  • Reduce noisy collaboration conflict notices and fix Sphere removal getting stuck.
  • Fix crashes affecting animated Neues and refresh automatic update progress reliably.
