I like how easy it is to use this app for appointments! It's very simple but also has all of my information stored in one place which makes life easier when trying new doctors or clinics (which happens often). The only thing about octo was having too many options at first as there are soooo may different ways you could set up an appointment/scheduled time etc., however once we got used them they were great!! We have been using their service since 2013 now without any problems - just keep adding more features if needed because everything works perfectly well right out-of box :) They offer free trial period where u get access tot he whole system including scheduling feature plus unlimited number off users who will be able t o schedule throughtout day from multiple locations within our organization.
