# How Alto Calendar works

How Alto Calendar works: the Busy/Free calendar, sharing and inviting, Today, widgets, Siri and Pro.

One Busy/Free calendar, shared with Apple's own calendar sharing. These pages show the rest, one part at a time.

## The Busy/Free calendar

What it carries, what it leaves out, and what counts as busy.

## Sharing and inviting

Three taps in the Calendar app, an invite from Contacts, and sharing back.

## Today and the timeline

Who is free right now, and the whole day at a glance.

## Widgets and the Lock Screen

Free time on your Home Screen, and a countdown until someone is free.

## Siri and Spotlight

Ask when someone is free, from Siri, Spotlight or Control Center.

## Pro

Everyone who shares with you, and the Lock Screen countdown. One purchase.

## Questions

Price, iCloud, what they can see, and Google Calendar.

## Share your free time on iPhone

What Apple's Calendar does on its own, and what Alto Calendar adds.

## Privacy

No account, no server. Your calendars stay in iCloud.
