It's also entirely possible that app doesn't play well with Kit Kat....
Well the main app doesnt either. Its up there. Under settings, app, running it says 1.1. I use to have like 1.4 when I had jelly bean and kit kat was designed to use less ram
Kit Kat was designed to be able to run on devices with less RAM, that does not mean it will not use more if available. In fact, it will when needed.
