Edit an .apk app soruce code

Hello. I'm looking for someone who can edit Tinder source code. Inside the app there are a feature that called "boost", when you click on that icon it comes a payment popup window to tell you pay for it. But is there someone here who are enough smart to change this source code that you can use this function for free without the popup window coming? also use this feature unlimited

I don't believe that will work, since it is checked on their server if you purchased or not.
