I like that it's very user friendly, we can input our own appointments with ease of use! It also has many different features to choose from which helps us customize what we need without having too much clutter in the system. I dislike that there are some things you have to pay extra money for such as text messaging if needed or more add-ons. With all these options though they do charge accordingly. So far so good but i'm sure this will get better over time. We're using AppointManager mainly for creating schedules for staff members. Our team at work has become more efficient due to this app.
