It does work on my iPod, but the page isn’t adapted for mobile.
You can delete things by double tapping, but the text explaining that you can delete things doesn’t appear.
In general, everything is too small to read and zooming isn’t very practical.

I changed line 512 in wpuf-functions.php to:
$extra .= sprintf( '<li><label>%s</label>%s</li>', $field->label, make_clickable( str_replace("\n", "<br/>", $meta) ) );
It basically replaces all \n characters to </br>
I also removed the colon, which was in front of it.
