The fact that I can create an appt from my mobile phone without having any appointments available - this makes it so easy when you are running late etc as well saving me alot money with no appointment fees (which would be quite pricey). It also allows us more flexibility about where our services take places which really helps keep costs down too!! Nothing at all unfortunately but perhaps if they were able integrate Skype calls into them? We have been using these tablets since 2016/2017 now however there has not yet come out anything new like integration between apps such Google Calendar ect..
