A good webmaster companion, Source Master is a web browser with minimal interface – just an address bar, refresh and go buttons on the top. The bottom of the screen has the clear and view page option. The purpose of SourceMaster is to show you source codes of web pages instead of the site (though using the view page option you can view the site).
You can even paste a url into the address bar. The app as free – but ad supported.
