This release does not have a Play Store Description, so we grabbed one from version 0.8.10:

NewPipe: A free lightweight Youtube frontend for Android.

Description

NewPipe does not use any Google framework libraries, or the YouTube API. It only parses the website in order to gain the information it needs. Therefore this app can be used on devices without Google Services installed. Also, you don't need a YouTube account to use NewPipe, and it's FLOSS.

Although NewPipe only supports YouTube at the moment, it's designed to support many more streaming services. The plan is, that NewPipe will get such support by the version 2.0.
