Hi guys! I hope everyone's having a great day.
If you're looking for ways to monetize or change how you've been monetizing your apps, I suggest you check out OfferDaddy. You can simply search them over Google.
I heard they have Android & iOS SDKs that natively integrate offer walls / ads to your apps so you and your users get money
I hope this suggestion helps your app develop this 2018.
OfferDaddy don't seem trustworthy at all - I've heard they create fake social profiles to pose on forums pretending to be members of the public whilst shilling their product.
Any developer serious about making money would stay far away from them.
Develop games in your browser. Powerful, performant & highly capable.
OfferDaddy Is A big NO NO
