accurate VPD app for android

[dean1963]

i'm using tent buddy on my galaxy but after looking at VPD charts on the web i'm seeing all sorts of different numbers.
the more i read about this new hobby of mine the more confused i get.
what apps are you guys using?

https://vpdchart.com/ is a good web-based app while VPD Buddy is a decent downloadable app.

I use both, while not 100% accurate they will give you a ballpark reading that will help dial in VPD
