It's very limited. You have to go through each booking appointment and put all of the requirements on each exact appointment. You can't universally add questions, reminders, or anything else.
You can't add customers or clients to your calendar without going through their side of the booking app. So you have the same limitations that a client has.
You can't reschedule a client if it's after the time that they should have been seen. Today I had an emergency and couldn't see a client we rescheduled for tomorrow but when I went in to try and move their appointment I can't. And it's my stupid software!
This would be very good if you're just having 15 minute or 30 minute free calls that you don't care about your clients because they're not customers yet.
But so far appsumo doesn't care about updating because it's such a cheap product. So they just keep it the same. And it's not functional for customers that you want to have a relationship with.
Two tacos for me because it is good for people that are trying to find potential customers but not if you care about the relationship of customers you already have.
