The Connected Farm Scout app does not have the ability of logging sampling points and assigning a number to those points. You still would need to use Farm Works Mobile for this type of logging. The Scout App is more designed to do weed/insect scouting as well as crop condition scouting.
Once prescription maps are created, if you need to send those to the JD monitors, you will need to use Farm Works as well.
The CF website and Apps are more supplements to Farm Works and not designed as a replacement to Farm Works.
