great idea . you are amazing , this builder makes everything easier 
It seems like quickappninja does not participate in this forum anymore… 5 days since I asked a question, and no reply from them here… =(
Hello! Ad revenue sharing is depends on many factors but in general it is about 20%. All income that will come from IAP is 100% yours cause you directly connects to Google Play dev account. If you don’t want to share revenue - you can use our service called - QuizStarter where you can setup all your own App IDs and show your own ads.
IAP feature activating is just one time fee.
We don’t sell source codes ;-(
Sorry for my delay in answer. I didn’t receiving emails about new messages in thread 
Sorry!
Anyway I’m here and will monitor this tread on regular basis.

Hey, just wondering how you make money?
Is there any way we can have a premium paid to use model where we keep 100% revenue including ads and in-app purchases?
Please confirm. I am bit confused with your revenue model
Looks great gonna try this one today.
We making money sharing revenue from ads. 80% revenue from ads is YOURS & 20% is ours.
In DASHBOARD you see your part of revenue.
This model force us to monetise your games with TOP PAYING ads so we are both wins!
Moreover in each game you can activate IAP module and receive revenue from selling coins. We don’t mediate this process and you receive 100% of revenue directly from Google Merchant.
If all this process is gonna be an online one or we have to download sort of an application or a software? In case if there is a requirement of a software then please inform about its price or fee etc
It is online drag-n-drop service.
