Once you become powerful enough, the add boosts stop working(but it still says enjoy your award), it lowers the amount of people you receive for example 3.5 ocd(A higher number) to 815.0 spd(a lower number) but you still have to pay the same price. When you turn it off it used to keep going but now it says it did but you come back to the same amount you left off to. it's not a bad app but it should stop shorthanding people in an attempt to make them stay longer. I'm not trying to hate.
