ROOLEE review for Tipo Appointment Booking

We use this app to help our customers book time slots at a photography space we own (ROOLEE Photo Loft). I love the easy way customers can select time slots and how simple the backend calendar is to view and alter. I wish there would be an improvement in the actual time slots. It would be nice if customers could select a time and a buffer window is immediately placed before and after the booking time.
