Travel apps : Normandy. I think you might find these handy
If you want a pragmatic ‘get-me-there-then-tell-me-about-it’ app, there are three main English language contenders – Spot On Location’s Normandy D-Day app (£2.99, iTunes store; Google Play before end of May 2014); Brittany Ferries D-Day Guide/Pocket Locations’ D-Day and Normandy (Pocket Locations have a distribution deal with Brittany Ferries for basically the same app; both £0.69, iTunes store); and Metropole Apps’ D Day (£0.69, iTunes store). While they all share some features in common, they all also have unique features.
