This app will no more be available to download from 31 July 2018. A newer version of this app is integrated already in the FieldClimate app (https://play.google.com/store/apps/details?id=com.metos.fieldclimate).
FieldAlert app is purposely build for users of iMETOS stations. It enables you to see data and graphs generated from your stations on mobile devices!
You need to be a registered user of fieldclimate.com, otherwise you will not be able to access any functionality.
