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