Grate for finding GPP
Grate for finding GPP but it would be better if we can use the app to find out the number of air movers and dehumidifiers to use. Otherwise grate app.
This is a great app... A lot better than pulling out a grains wheel!
It seems this app needs updating to ios11.0 it no longer works on either of my iPhones
Sure would love to see it updated
