I could have written the same post I had a niche app, it put it free, it made also more than 2000 download everyday. So why not making a game… ? 9 months later, working some weekends after work, my first game was born with the same numbers: a few downloads, a few cents earned.
It didn't stop me, i released a game a week ago, no matter how hard i tried contacting review site or any other marketing thing… within a day or two, the game becomes invisible, new released game spots are taken by hundreds of 'new' apps, among 10 candy crush copies (from 4 differents companies, with exactly the same screenshots and icons…).
Some years ago i also wanted to earn enough and live only from my own work. Hopefully i didn't quit my full time job… And i changed a lot my expectations about the store. The game i released some days ago didn't took me 9 months, i just enjoyed doing it.
Actually i now see my 'indie' work as a big visit card. I have the chance to have a job, and enough time to develop games/app. I earn a little money from it (enough to continue and dream about millions of downloads), and most of all, i also received several job offers from people seeking for some skills (direct contacts from linked.in or viadeo). Maybe one day, one app or game will really work, or i'll be contacted for a new job, or my 'indie' work will help me to apply for a new one … Showing my website site with my apps and games (http://www.sovapps.com) has always been very well welcomed during interviews…
well it's not negative at all, and in my case i don't really need money from my apps to live, but i just know i won't spend a whole year on a game.
"if you can't make money on IOS ecosystem, what makes you think you will make money with android" : i would ask, if you make money on iOS, what makes you think you will make money on android ? from my own experience, one app i have on iOS which is making some money, is not at all on android…
