I'd like to exchange free app reviews, my app is https://itunes.apple.com/app/superpin-drop-pins-through/id934162133
(supports iPhone and iPad with GPS).
It's for free in the app store until May 5.
Let me know if you're interested and when you've rated my app, send me a link to yours and I will return the favour.
Ah right, I'm in the German iTunes Store and I've an iPhone 5 and iPad Mini.
