You made 30K; good for you and congrats. Why all the snark here?

Simple and mindless(pardon not meant negatively) sells. Make apps for the audience who buys apps; males 18 to 34(though 34 might be a bit high) if you aim is to money. Something that makes people laugh and want to share it with their friends who buy it and share it with their friends and so on. iFart & Fat Booth(though idea is mindless but tech isnt) are further examples.

Your demographic may be off. I sell apps on Android, and I am pleasantly surprised by the number of women who buy my sports related apps.
