Moble application development

What are the technologies used for mobile application if i know web development ?

Hi there. The short questions you have posted on this forum are way too generic for anybody to give you meaningful answers. In fact, the only possible answer is to use google and start learning things yourself. You may want to search around for classes on web and mobile development, too. Or be more specific, describe what you want to achieve, what you know, what you expect to learn, etc.

Good luck!
