I realize that the patent was filed in 2012, but there's plenty of prior art. For example: https://itunes.apple.com/us/app/type-n-walk/id331043123?mt=8 The whois for type-n-walk show it was created 2009. And archive.org (https://web.archive.org/web/20091006131301/http://www.type-n...) shows that there was actually an app in existence at that point. -
