Who are you targeting the app at? If its that good and it's a game and you gf is really good at UX and you release it then a bigger game dev house could copy it and they have the network and bucks to advertise it in other in-game advertising.
It doesn't help you say it is so good rather your target market has to like and use use it. The big problem is with apps is people install and use it once and not again. If it's a game I would side load it on a couple of kids phones or give them tests phones and get them to give your feedback before you go decide to go live. A South African is not going to copy your idea. An overseas guy might so once its on the store there is no going back.
IMO With games I would think v1 has to be very good as you only have one chance. With other type apps v1 doesn't have to be perfect and you can incrementally improve it.
