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.

The desktop app now has a broader first-run setup, stronger onboarding, and clearer workspace navigation for threads, spheres, memory, workflows, settings, and trust controls.
Spheres make it easier to organize work, keep threads scoped, and manage nested areas of responsibility.
Chief of Staff workflows now cover operating records, source transparency, secrets, connector setup, and approval-oriented review flows.

Chat and thread experiences feel smoother, with cleaner answer reveal behavior, better markdown spacing, stop controls for running threads, and improved activation when starting or switching conversations.
Settings now cover profiles, appearance, model routing, integrations, secrets, workflows, update controls, and companion pairing in a more complete desktop surface.
Workbench and memory areas now support richer source import, file attachments, document intelligence, search, recall, and review of proposed memory.

The iOS companion adds paired mobile chat, QR pairing, thread search, thread rename and actions, ToDo threads, sidebar improvements, and live activity display.
Mobile settings now mirror more desktop configuration, including profile, appearance, model routing, workflows, Brain sources and memories, connectors, secrets, and Sphere Agent settings.
Mobile companion actions now support editing spheres and workflows, reviewing delivery approvals, managing memory, and removing sources.

Chat streaming and handoff behavior has been tightened across desktop and mobile, especially around new threads, final answer reveal, typing state, and live routing while answers stream.
Beta release delivery is more complete, with public release notes, latest-download support, signed release packaging, notarization preflight checks, and safer release artifact handling.
Companion relay syncing is more resilient, with pairing, redelivery, activity updates, revoke checks, and polling behavior improved for beta use.
