Tried it, but ultimately deleted it.
I’m a local Santa who books time for personal, home visits during the Christmas season. This seemed like a great idea, but it is just not flexible enough for my use.
From instance, my visits are in increments of 20 minutes, but this service is limited to ONLY increments of 15 minutes. And, I only do visits from 11/1 to 1/15, but take requests for that season, year round. This service requires me to custom configure each (76) day/date individually, in order to accommodate this. And, the client must scroll to the day/date they are interested in, a tedious one-day-at-a-time (it’s designed for “the next available appointment”). And, Since I make “house calls”, I need to make allowances/gaps between visits based on drive time from the previous visit (something Apple’s Calendar does, but this doesn’t). No can do. And… well, you get the idea.
This might make an acceptable solution for barber appointments, but the more flexibility you need the less acceptable this becomes.
