Modifying / Cracking a specific app

Hello all,

I've gotten a new app for my android called "CoinOffers".. yes, it's for McDonalds :P

You can use coins to buy food from there, but coins are only released a few times on a year..

Some of my other friends got it cracked for iPhone, so they can just enter any amount 1-1000 coins in their app, and then they got it!

So basically free food, which is pretty awesome

I was wondering if anyone knew something about cracking an app, or how to modify the amount of my coins (ANDROID)?

PM or reply here in thread please

Thanks in advance

Is your phone rooted?
If so you can try game cih. You might have to go in and edit its name due to many apps blocking it now adays. If you need help on it that just ask. Cih is just like cheat engine for your android though so you should be able to do that easily. Or your can always reverse the app and then make your own ways to add coins if cih wont work for you. Thats a whole lot more complicated though.

Sorry for late reply:

No it's not rooted, but I guess that's not so hard to do ?

And haven't tried "cih".. dunno how to use it or anything >_>
