BTA Appointment Booking App

We have used BTA for over 3 years and it's the only booking app we have ever used. Simple to set-up and very good interface on the customer side and on the store side. Customer support is extremely responsive and any issues are quickly resolved. My one wish is that there is a way for google analytics to integrate with the app. As soon as a customer begins the booking process on the BTA side, we lose side of customer conversions.
