The SUBWAY app, from the sandwich store franchise of the same name, provides an easy for UK consumers to put a digital version of their SUBWAY SUBCARD (loyalty card) on to their Windows Phone handset. The card lets you collect points when you make a purchase in a SUBWAY outlet, which can be exchanged for rewards (e.g. a free snack for 200 points).

The app can also be used to place an order for pick up from your local SUBWAY outlet. First you'll need to specify a specific outlet and pick up time and then the app will walk you through the various order options (sandwich size, type, extra toppings, seasonings, drinks, side-orders and so on).

Once you've placed an order you'll need to get on your feet and go and collect, and pay for, your foot long sub, but you can feel smug about the fact it should be ready and waiting for you. 

Do note that this is a UK specific app, and currently only covers SUBWAY outlets in Greater London, although the developer does plan to add support for additional regions soon. A separate SUBWAY app for select other markets (including New Zeland) is also available from the Windows Phone Store.
