Best dressage app?

[starryeyed]

Which is the best app out there for learning dressage tests? (Preferably not too pricey!)
It takes me forever to learn them and I think an iphone app may be just the thing to help me remember them as I can look at it whenever I have a spare minute in the day. There are quite a few out there so would love to hear your recommendations/favourites? X

There's an App for that?

Type in dressage to the App Store and it comes up with all that are available, there's one which is 69p which is quite good.
