## Alto Shared Time Calendar Description
Share when you are free, without showing what you are doing.

Alto Calendar builds one Busy/Free calendar out of the calendars you already keep. It carries only the blocks: when you are busy, and when you are not. No titles, no locations, no guests, no notes.

Then you share that one calendar with your partner, your family or a friend, using Apple's own calendar sharing. They see when you are free. They never see what you were doing.

They can make one too, so you can both see when everyone is actually free.

- one Busy/Free calendar, built from any calendars you pick
- event details never leave your device: only the blocks are shared
- see today and tomorrow as a summary or a timeline, with everyone's blocks merged
- declined invitations and anything marked free are ignored, so you are not shown as busy when you are not
- all-day events are ignored by default, and you can turn that on
- refreshes in the background as your calendars change
- ask Siri “When is Sarah free?”, or check from Spotlight and Control Center
- invite from Contacts; the person you invite is shown how to share back
- no account, no sign-up, no server. Your calendars stay in iCloud, where they already are

Free to share with one person. Alto Calendar Pro, one purchase, shows everyone who shares with you and counts down on the Lock Screen.
