Name: Normandy D-Day 1944
Available for: iOS
What it does: Offers practical travel tips as well as historical information for visiting the five invasion beaches as well as 100 other locations throughout Normandy. The information is categorized and color-coded by topic: museums, battlegrounds, memorials, cemeteries and historical interest.
What's hot: The content was written by journalists who specialize in battlefield tourism, and every location has been visited and researched by the developer On the Spot Locations. There are also 500 photographs you can zoom into. You can access the information offline and use it online as well (but watch out for roaming troubles). Make sure you take advantage of the "Favourites" section so you can plan your trip in advance.
What's not: It took me a long time to load the app. It is more than 50 megabytes, and you need a Wi-Fi connection to download it. Make sure you do this at home before you take off on your trip. It will save you time and, most likely, be quicker than using the hotel Wi-Fi.
