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

  • Create Spaces for shared conversations, invite participants, post messages, use replies and reactions, and search across conversations.
  • Let Auto choose an available model for each task, with routing preferences, provider limits, and clearer fallback guidance.
  • Manage notifications from a desktop inbox with granular preferences and per-thread controls.

Desktop

  • Dictate prompts with active recording controls, setup guidance, and clearer feedback.
  • Create, edit, run, and delete routines from conversations, including authenticated webhook triggers.
  • Add verified account emails, combine eligible accounts with consent, and manage addresses with explicit confirmation.
  • Conversations preserve reading position more reliably and provide a quick jump to the latest messages.

Companion Sync

  • Spaces, settings, read state, deletions, and messages sync more reliably across connected devices.
  • Newly shared Spaces can appear without restarting, and interrupted invitations resume without resending completed invites.
  • Saved device connections remain visible while cloud details refresh.

Reliability

  • Slack replies stay in their original thread with better conversation context, while Discord reporters can receive shipped-fix updates.
  • Image attachments and previews remain available more reliably during active conversations.
  • Interrupted or long-running agent turns recover more cleanly, and shared conversations better resist stale updates and sync conflicts.
  • This remains an alpha release, so collaboration, sync, and newer desktop surfaces may still have rough edges.
