I am extremely happy that I can book directly from this app, but there is no way to adjust timing for services, which means that it is difficult to customize appointments remotely.
There should also be an easier way to edit the time/date of previously booked appointments without completely cancelling them, and then rebooking them. This is actually a really big pain if the timing was customized on the main computer, then a change needs to be made remotely.
There is no access to client profiles, so I am constantly having to lean over the shoulder of my busy front desk to get color formulas out of the main computer. All of those things tend to make this app sort of ok, but actually not terribly functional.
