The 1 Mar 2020 version of my book Space Apps for Android: Discover the Best Astronomy and Space Apps is out. The main change is the new entry for the Nightshift app in chapter Ephemeris. More details are in the release notes.
The book will let you learn what these apps do and how to use them. Here's the cover in the Google Play Books app on my Lenovo Tab E7 tablet.
