Pro Helpful support
Pro has every function you need and more, incredibly easy setup guide when you create the system
Even with the app missing, this the most userfriendly system I have tried so far. When creating the system, you follow a very simple guide, that walks you through all the system's modules and functions, and allows you to customize it all to fit your needs. Also, you can easily get the app icon on your phone, that opens up the system in your browser when you click it. It works just as good as an actual app in my opinion.
Cons
Con no app, still easy to use from the phone though.
The app missing is not a huge problem for me at all. They have a guide for both Android and Apple on how to get the icon on your phone's homepage, which works just as fine. The only difference is that the system opens up in your mobile browser instead. It almost looks like an app.
