>DrawQuest got some traction, but found that selling paint brushes in a drawing app is a lot harder than selling extra lives in Candy Crush.
Selling brushes in a drawing app makes it seem like you aren't taking your customers seriously. I know it worked for Paper, but they aren't going to get any of my money any time soon. I've purchased several IOS and Android drawing programs, and several significantly more expensive programs for PC. I wont, however, purchase a productivity program with in-app purchases. Just tell me how much money you want for your program and I'll buy it. Companies should quit coming up with idiotic monetization strategies designed for the sole purpose of tricking customers out of larger amounts of money.
