Great App, But Still Lacking

At first I was excited about this app as it seemed easy to set up, and so many great features, but there are still some issues that need to be worked out such as iPhone app doesnt alert you when a customer signs up for a class. You only get an alert when you get a new client. Also, Im having to go into the laptop version just to check every couple hours to see if I have to go into the office.
Appointments vs. classes gets a bit confusing...
Also, it originally said you could integrate Square payment systems with it, but now you cant.
If this were fine-tuned a bit it would be the number one app for many, many businesses!
