Apple Calendar

Local Apple apps

Your day, understood, and nudged at the right moment.

Halo reads your calendar through the same built-in macOS framework Apple's own apps use. That means it knows what's next, can brief you on your day, and can nudge you just before a meeting starts.

It works in both directions: ask by voice or chat to create an event, look one up, or respond to an invitation, and Halo handles it, with a confirmation before anything changes.

Capabilities

What Halo does with it

How it connects

Built into your Mac.

  1. 01

    Nothing to sign in to

    Halo works with Apple Calendar through the same built-in macOS capabilities Apple's own apps use. There's no account to connect and no key to store.

  2. 02

    macOS asks first

    The first time Halo needs access, macOS shows its own permission prompt. You decide, and you can revoke it any time in System Settings.

  3. 03

    Nothing leaves your Mac

    Reading, writing, and understanding all happen on your device. There is no server involved, not even ours.

What stays private

Your calendar is read on-device through macOS's own calendar framework. Events never leave your Mac, and macOS asks for your permission before Halo can see them at all.
