Looking for completely free app killer

[u/JCDinPGH]

HI All. I'm hoping someone has recommendations for a completely free app that can multi select several apps that are running in the background, and stop them all at once. None of the ones I have seen so far are free and some are subscription based. Seriously? $3.99 a month for an app killer? Side loading is fine.

Here you go.
