actually I've done this report in 2011 and 2012, and at this time this was really a good question because there was not so much competion. Nowadays as maxerison unerlined, there is a lot of competition (and I'm happy to still have a good visibility). I was even wondering if it was interesting to publish my report this year (I mean not only for my ego) but several devs told me that it was inspirational and give them energy to read such posts...

PierreA, it was indeed inspirational. Partly because you're immensely talented. It's easy to make utilities with programming chops. But you made something so much more, you made an artistic, learning, _EXPERIENCE_. Kudos Pierre, your apps are super high quality and the colors are just blooming, very fun stuff, even for an adult like me to just mess around and watch the pretty colors fly around, or the ball physics. Cheers mate.

Thanks - it's just because I'm still a kid somehow, so I like it to be fun for kids like me ;-) For the UX, I worked in this field so I've got some experience/feeling/theoric knowledge in this field. Pedagogy knowledge comes from having homeschooled kids - you need to learn (and also you experience) how kids learn the best way.

I'm glad you chose to publish the report, as even skimming it (will read thoroughly later) I found it really useful. It is great to see some real-world figures about what app makers are able to earn.

Oh wow, now that I actually hit the article, I remember at least one of the previous articles! Congrats, glad to see this is still going strong!

If you'll only spend your time working on a product for some niche that no one has found, you'll end up with nothing. Competition is inevitable, so it's best to face it and never fear it.

Well I work in a niche with lots of competition, some of it strong, some not so strong. I'm not convinced that I'd want more of it though.

Yes its a fundamental precept of any new business idea that existing competition validates the idea, it doesn't shoot it down.

It wouldn't matter. He's got the ball rolling & momentum + brand recognition. It would take as long if not longer for a newbie to try & copy his methods. Even if they do, it doesn't mean you'll succeed or even persist through adversity.

I bet they already have plenty of it.
