Can anyone recommend an Android app to scan other apps for ad libraries and report which libraries are used by which apps?

I had an app, I think by Lookout Security, that did exactly this. It worked wonderfully. But they stopped updating it, and then it was dropped from the Play Store.

I am looking for an app that has been updated to handle current ad libraries.

An app that requires root privileges is acceptable.

Gratis is preferred, but not required. Same with open-source.

There are several of those – but it indeed looks as if everyone stopped updating them. The one from Lookout had good details.

One of the few that still seems to be updated is Denper's Addons Detector:

menu filter filter
Addons Detector (source: Google Play; click images for larger variants)

Not only does this app let you scan for ad libraries, but also for other development libraries, analytics and more. It's also a permission browser. This is currently the best rated app in this section, and was last updated less than a month ago – while being around for about 5 years.

My long-time favorite (next to yours) was Appbrain Ad Detector – which unfortunately wasn't updated for two years (I still hope they pick it up again):

menu concerns concerns concerns
Appbrain Ad Detector (source: Google Play; click images for larger variants)

Here I like the clean interface. This detector also lists plugins from social networks separately, shows which permission combinations raise concerns, and of course lists the ad modules, developer frameworks etc. If you use the Appbrain app to access playstore (it offers an alternative frontend), you are even informed of those before you install an app.

Both apps are available for free. I cannot tell how up-to-date their library knowledge is (especially concerning Appbrain's app, which was not updated for 2+ years), but would expect Denper's to be in front here.
