Looking for an app similar to market helper

Hey, I am looking for an app similar to market helper so I can spoof to another device as market helper has this feature but isn't working. I'm doing this as I want to get amazon version of the madden mobile apk but for some reason it says my devices aren't compatible. If there isn't any app like that is their thread that post free game apks? I know there is one for the play store but couldn't find one for the amazon app store
