Yeah, I downloaded BitMaker too. 30 minutes is the normal one, but you can also use booster to reduce it to 10 minutes for the whole 2 hours (you have to pay 450 satoshi for the booster though). Payout is 50000 and it is once a week, if I'm not mistaken its on Saturday@ Sunday.

I also downloaded 10 apps from single developer, you can search on google play apps like Bitcoin Booster, Bitcoin Kitty, Bitcoin Fire, Bitcoin Fighter and then download all 10 apps from the same developer. The account will be integrated and it is easier to claim. The best thing is you can claim EVERYDAY once you reach the minimum amount which is 100000 Satoshi
