I think they're mostly just ported. I've bought a few of the Square games on iOS and they were just the normal games with touch capabilities added on top of the old menus. No usability changes at all to accomodate modern touch patterns. There are many "click" needed to navigate some menus, which would just have been one touch or drag in a modern app. Scrolling was also laggy and glitchy.
