Sticking my neck out and asking a question that might see obvious, but, what is the difference between an App and a Widget? I assume the function differently or they wouldn't have different names. Yet, when I look at the stuff I have on my screens, they look the same. Someone told me to get rid of my Widgets to reduce lag. (I plan to keep my widgets because I only have 4, I think, three toggles and one weather.) But, why would Widgets create lag and Apps don't?
