What phone do you have?
motorola Moto G (5S) Plus (Android 8.1.0) v3.0.0-en_US

Describe your problem in detail: What geoid and datum are being used? The values I've been getting are about 50 to 100 feet below what it should be with wgs84 and other topo map elevations.

Hi,
it's WGS84. Are you talking about elevation or horizontal location? Elevation is very imprecise.

Describe your problem in detail: I like the app.  I was talking about elevation( vertical ). I realize that elevation is not as precise as horizontal positioning; however, it is consistently lower than averaging with my Magellan Triton 2000, and app " My GPS Location". Thanks for your interest.

Hi,
I no longer maintain the app. But it's open-source here: https://github.com/davidvavra/gps-averaging If you send a PR, I will merge it and release a new version.
