Calculier - You can go and download dozens of other calculators onto your phone to do exactly the same thing - calculate numbers (of course). Each one of these will pretty much look exactly the same, and work in exactly the same way
Cheaper - This app is made for comparing tricky prices. This is useful when you have doubts if a 10 dollar coke of 1 liter is cheaper than a 12 dollar coke of 1.5 liters. You can use any currency and quantity as long as you know that both use the same measurements
Double Out - This application will help you with dart finishes. In Dart games like 301, 501 and 701 you must end on a double. There are two and three dart finishes starting at 170. Many pubs have posters up that show you the best finish given what you have left to shoot. This simple application brings that information to your Windows Phone 7
