Ski TrailMaps (Android only)

What this app lacks in features it makes up for in comprehensiveness. The app contains piste maps from resorts around the globe, from the mega-resorts of Three Valleys and Whistler to smaller areas in Argentina and Macedonia. You name it, they have it.

Maps need to be downloaded before you use them for the first time, so make sure you do this before hitting the slopes. The maps are the basic piste maps which limits their use when you’re out and about, but it’s useful for planning your route without having to unfurl the giant paper versions available around the resort. The pro-version has more features such as allowing you to check out webcams of the resort and weather reports.

Ski TrailMaps is free but can be upgraded to Ski TrailMaps Pro for £2.99

Download from Google Play.

Ski Maps (iPhone only)

This app doesn’t include quite as many obscure areas as Ski Trails but the areas it covers are done so in far more detail.. It can use your GPS to place you precisely on the map – especially useful if you’re moving between piste and off-piste.

It isn’t free but combines precision with most of the major ski areas in the Alps and the USA – if you want to see the conditions before you venture out you can even check the webcams stationed on individual runs.

SkiMaps costs $2.99 or £1.80.
