Replying to New iOS-app for skiing

In a few weeks we are launching a free app called Trickbook.
It is a beautifully designed application, which serves as log book and reference for all tricks on skis. That means you can tick off rail and jump tricks as you learn them, to track of your progression.

Right now we want to research the market to see how we can improve the product, and this is where we need your help.

Please write which features you would want to see, and we will be very grateful.
