App killer for android

Anyone recommend a decent one, the hearing app tends to run permanently in the background even when I'm not wearing them and doesn't seem to have an off switch

Can't you just uninstall the app?

Sorry that should say hearing aid app, so it's needed.

Can’t you just close it?

Also why does it matter, it’s not doing anything
