The ability to send out reminders through text messaging or email as well has being able t have our appointments show up right when we want! I love this service because there are so many different options available within one platform which can be confusing at first but once you learn how everything works together they become very useful tools!! We also like having access from any device since sometimes things get lost between devices/tablets etc.. This helps us keep track more efficiently even if someone forgets about an appointment here's hoping no other problems pop into my head haha.
