A while ago I set out to build my third mobile application. Only this time the client wanted not only an iPhone app, but one for Android too. So that's why I turned to Appcelerator once again, after my failed first attempt. In case you don't know what...

I bought this book, hoping it would give tips and hints on making effective user interfaces, what works best, what tools to use, how to make effective wireframes, give example screenshots, etc. Let me tell you this first: it's not that kind of book.
