ios7 appears to have broken input fields for a number of web applications. Input fields now take two taps to allow the user to input data even though the keyboard is brought up after only one click. Here’s a hack to fix the input fields for any of your webapps ios7 broke.

if(window.navigator.standalone) {
    var arr = document.all.tags("input");
    var len = arr.length;
    for(;len--;) {
        arr[len].addEventListener('touchstart',function(ev){
            var tel = ev.target;
            setTimeout(function() {
                tel.focus();
            }, 150);
        });
    }
}
