How do I see what .bar & .apk applications are running on my Blackberry Q-10?

I am still on 10.2 right before 10.3 version. Is there an app to do this and will it also show APK files that are running, I would like a way to be able to see what is running as in .bar and .apk files as my battery life has become sub par out of the blue and I know it is because of applications (as in my fault) so would love a way to be able to tell what is running and shut them down as in .apk and .bar all in one. I do not mind paying for an application like this if there is no easy way ever since snap.

You can see the running apps using the native App Manager accessible from Settings
