I have been developing odd-ball physics apps (ThreeBody, Geodesic Asteroids most recently).<p>I'd say I put in about 10 hrs/week => 520/yr.<p>Last year my revenues were up 400% (to $88) with expenses of about $400 (apple developer fee, web host, test device, couple of books) - so a loss of about $300.<p>Time/revenue = 88/520 = $0.17/hr
Infinite. Can't make many things public nor open source either because nda, non competes or because I didn't ever put them past "it could work" phase. Mostly the latter to be honest. Figuring solutions is so much more interesting that working out kinks and corner cases
Until the last few months, the ratio was stupendous: ~$300/hr<p>I've been working on upgrading the technology and business model. It's a risk and I think I'll fail...
I have an Android and iOS game that took me around 125h to do (including learning time).
In the last 12 months it made around $25000, so about $200 per hour.<p>I'm not counting with time spent maintaining the game, but it should come to about 2~4h/week in the last year or so.
I have a project that I now maintain on just 2 hours a week... But I worked on it for 4 weeks, 10 hours a week...<p>So that is 136hr/y.<p>Revenue for the past 12 months is £26,500<p>26500/136 = £195ph
