thank for sharing. it's surprising that nearly half a million downloads translates into such a small amount of revenue. is this the nature of in-app advertising, or is this because the number of active users of the app is much smaller than the number of downloads?
my app's a bit special - it's purely SDL / opengl / C with a tiny java wrapper just to get going. TBH, there's some key technical problems with it with respect to onboarding, and because of those problems and likely technical problems there's <20k installed users.
It's DJPad, feel free to try it - the library functionality is embarrassingly bad but the audio engine and UI's half decent.
Probably the biggest feature is that it's lower latency than the competitors written in java. It doesn't hold a candle to any of the DJ apps on iOS whatsoever though.
I started a new job/career 2 years ago, and now I'm a dad - suffice to say my free time is gone. If I had stuck with this project I would have rebuilt the library and built a dedicated onboarding walkthrough.
I've made $1500 in the past month on my Android apps. I also did some additional Android stuff with a partner, so that would be another couple of hundred dollars on top of that.
All from ads. Mostly Admob, but also Millennial Media and Inmobi.
The free version has had 483k downloads, makes ~5$/day advertising (admob/adsense). ~250 downloads a day, been on the market since 2011.
The paid version ($2.99) has had <2000 downloads over the ~3 years it's been on the market.
Unfortunately I've no time to keep it updated so last update was in 2012.
