How do I create an app , like doodle jump or angry birds because I have an idea just can't turn it into a game cause I can't find software to make it on?

Doodle Jump and Angry Birds are pretty complex games. You can read this post to know why Angry Birds became so popular http://www.pcmag.com/article2/0,2817,2392794,00.asp Having a great idea is great but to create something even as popular as 10% of the two you mentioned, you need to have people who share the love for your idea and have technical/creative/management capabilities for the same. Guessing from your question, I believe you don't have any technical background. You need to build upon your idea and define it properly. Then go out and look for people who can help you in developing the idea into reality. As Brad mentioned, create a story board, mock ups etc so you can show it to investors and pitch for it, in case you need investment as well. Creating a game is complex so make sure you get some knowledge about concepts first and then go on to make something extraordinary. All the best from my side!

Try using Corona Labs Software($350), once you learn the api you can use their templates to create all the Angry Birds and Doodle Jump clones that your heart desires!  Learn to use inkscape(free) to create engaging backgrounds and characters,  go get your Apple Developer License($99),   and their you go baby!
