Is there a service that rates app security/permissions? Is there a service/company/app that vets Android apps and reports on their "trustworthiness"?

I recently moved from Blackberry to a Galaxy S2 which does not have an LED indicator light.  I searched the market and found an app that is highly rated and uses the screen to mimic this functionality.  This app requires an abundance of permissions that I don't see a need for.  I don't want to compromise my data if 

I understand that the granularity of permission-granting leaves a lot to be desired, so I'm hoping there's a service that rates whether these apps are "good actors"...
There's one called Exodus Privacy which has both app (open source) and website https://exodus-privacy.eu.org/en/page/what/
One downside: it scans only apps available on Google Play, you can't upload apk manually.

Here's an example of it's report on one of popular browsers:

I prefer to use it together with Yalp Store app (free and open source) which allows you to download apps from Play Store without google account and services and has built in support of Exodus Privacy on app's install/update page:
