This app does exactly what the description describes, no more and no less. It allows you to connect an EXTERNAL GPS DEVICE to the USB port of your tablet and to pass the data from it to any other app. It does not magically provide INTERNAL GPS to tablets that don't have it (such as the Kindle Fire). It is not a standalone app, you have to have an external USB GPS device such as GLOBALSAT ND-100 USB GPS Dongle Receiver For NetBook,Laptop,Notebook,XP,Vista. It does NOT claim that the app works on all tablets - that is probably why it is free! I find that it works on my Nexus 7, but not on my MID tablet.
