Building apps

Hi, I am a doctor interested in building health care apps. Which coding language do I need to learn ? Will appreciate. Thanks, K

Well, that depends. You can use phonegap (which uses, html, js and css) to build apps, but if you need a big app, you don’t want to use this. App for what? mobile? In case of android you need java, for ios you need swift(2) and for windows phone you need c#

Or do you want to build a webapp?
