It's easy to use, its simple to create bookings, I like that I can print invoices and have them sent to customers. I have not used the other features of the app but I hear they are great. I wish it took a little longer to create an account and the customer service is not great. There are a lot of other apps out there that are just as good and even better. We use Bookmemate for booking appointments and sending invoices. It is easy to use and I don't have to worry about the invoice being sent out
