Your family sees when you're busy. You see when they are.

The double-booking problem

You say yes to a 4:00 client while you are between appointments. At 3:50 your partner texts to ask if you are on your way to the 4:15 pickup that has been on the family calendar for two weeks. Now someone is getting a very apologetic call.

The fix isn't another calendar. It's seeing the one you already share with your family at the moment you are deciding whether to book.

See their calendar before you book

When you schedule in Solo, the events from your family's shared calendars appear below the appointment form for that day. If the dentist is at 4:15, it is sitting right there before you tap Add. You pick which calendars show up, so you can include the family calendar and leave out the one that tracks the neighborhood recycling schedule.

They see your appointments

Because every appointment is a real calendar event, you decide who sees it with the calendar sharing you already have. Put appointments in a calendar you share with your partner and they see your day on their own phone, in the Calendar app they already use. Keep appointments in a private calendar and share a separate one for family plans if you would rather keep client details to yourself.

No app for them to install

Your family doesn't need Solo. They don't need an account. They keep using the Calendar app on their phone, and it keeps being right.
