Great if you only have one device, not so if you on multiple devices

This is 2015 most people have several devices such as iPads iPhones Mac computers and so on.I cant get it to sync with any of my other Devices iPhone, IPad, MacBook Pro, iMac since it only seems to work on one device I dont see that it has much advantage over just putting everything on a flash drive and locking the flash drive away. Or at least with a flash drive you can carry that in your briefcase or pocket and carry it to any Device that you want to use it on that has a USB port. Regret wasting $20 on this app. Maybe I just havent figured it out yet but if its this hard to figure out I probably never will. All of the other apps that I purchased from the Apple Store have been super easy to sync with other devices. Be careful before you waste $20. They dont even assign it a ticket number when you contact them they just give you the we Will get back to you as soon as possible. Usually that means the 12th of never.
