Calendly is easy to use, but it isn't compatible with Apple Calendar. If you can fix that, it would be a GREAT app. But it is forcing me to consider consolidating everything into Google Calendar, which has a Calendly-like booking capability. Frustrating. But if it's a cheaper solution, worth considering. Calendly, I don't want to break up with you. But I may have no choice if you stay incompatible with Apple Calendar.
