#WIDGETS I LIKE:

#DEVICEINFO (com.ytheekshana) v3.4.2.1
1x1 RAM widget.

#WEAWOWWEATHER (com.weawow) v7.1.3
Highly customizationable. Tweaks to display. Wind speed, Wind direction & Wind Gusts.

#MOON (de.cassiopeia.physik.astronomie.mond) v1.6
Nice Widget. Low RAM use.

#MOONPHASE (com.moonphase.b_watchwidget) v10.75
Alt. Nice Moon Widjet.

Note: I use #TrackerControl (net.kollnig.mission control) to eliminate any app tracking. You also may be able to rebuild the app using #LuckyPatcher.
