Remember the days when to look at a map you had to unfurl a huge piece of paper and work out exactly where you were based on the position of local landmarks? It's likely those maps were produced by Ordnance Survey.
The Southampton-based mapping company is now bringing its incredible collection of cartography to its new app, which looks incredibly detailed and is aimed at cyclists, walkers, runners and any other outdoors enthusiasts you can think of.
It's free to download, but if you want the most detailed map available at your fingertips you have to pay a subscription fee.
You can access digital versions of all 607 Explorer and Landranger maps in the OS collection, which represent total coverage of Great Britain.
The subscription also allows off-road routing options in all 15 of Britain's National Parks and will soon be available for use offline so you can use it without destroying your data plan.
If you want to subscribe for a month to cover your holiday it'll set you back £3.99, while an automatically renewing 12-month subscription is £19.99.
