I also use the GTD method, but with Remember the Milk instead of Evernote.

Here's a good blog post that shows how to implement the GTD system with RTM: http://blog.rememberthemilk.com/2008/05/guest-post-advanced-...

RTM has a web app for regular browsers and mobile apps for both iOS and Android. There is also an extension called "A Bit Better RTM" for Chrome/Firefox that adds nice tweaks to the web app.
