App or Setting for showing app title when IN app?

[AC Question]

I'm new to Android and smartphones, not adroit with it at all. Kitkat 4.4 btw, not upgrade-able here. So many times I find myself accidentally in a screen with some prompts/settings/etc but I have no idea what the App is, there's no visible Screen Title. Have to Save the Space, you know!

So I wonder if there's some setting or even an app so that I can see what app I'm in. The Home or Back buttons don't help, even the Recent button shows obscured info.
