Do I need to download anything to make it work
Do I need to download anything from the DMP website to make it work?
The App uses DMP data (under licence). You do need to download and update this on a regular basis.
Updating is as simple as selecting the “Update Data” option from the main screen. The App does the rest, Downloading and processing the DMP files for use in the App.
You do need an internet or phone connection with data to do the “Data Update”
