I really like developing either apps and games in my spare time. Pixeldb was the first iOS app that I released on my own. It was a great learning project, doing everything myself incl. programming, design and graphics.
The app was a pocket database for everything related to video games - think iMDB but for video games. You could track upcoming releases and the games you own and have played. I didn’t create all the content, for that I was relying on the great community of Giantbomb that has an amazing wiki of content.
