The ease of scheduling an appointment, keeping track of all the info and the ability to share it via email or text. I wish there was more flexibility with time slots and appointment reminders. I also wish it would sync up better with my calendar (calendar syncing is important for me). It's great for those who are always on the go! Being able to schedule appointments and keep track of them has been made so easy! This is definitely one of the best features we've used in our office. It's easy for me as I am not tech savvy at all, just using it once in awhile when my phone dies or something happens where there are no other options available! The app itself can be difficult sometimes since some of us don't have great eyesight (me) so we need help figuring out how things work if they aren’t very clear about what needs done before hand/afterwards etc.. Sometimes our phones die too which makes this even more frustrating!! But overall its been pretty good considering everything :).
