Android Application Development or iphone Application development???
Which Apps are more useful and cool???
It's not a question of which one is more cool. Things to keep in mind when you get into mobile development.
-What kind of a phone do I use? (Android or iPhone?)
-What OS does my PC have? (Android can be developed on any OS while iPhone Apps may not)
Ideas for a "useful" app. When you are doing your daily routine and realize that it could be done easier or with your phone do it.
For example: If you you need to do metric conversions often just make one yourself to get acquainted with mobile development and then move on to the harder stuff later on.
Well, me personally, I think you should stick with the Android apps, simply because that they WILL reach a broader audience, because they are a phone. Not just one phone, like the iPhone, but many phones, ranging from different phone companies. More android will be made, technically, then the iPhone
