Stationary Bike Fitness App?

Hi there guys and girls. I'm just looking for some help. I like to cycle but sometimes I find it hard to motivate myself to use my bike, especially while the weather is still cold and wet. But I have an exercise bike at home to combat that. What I was wondering though is does anyone know of an App I can use to track my workouts on the stationary bike more accurately? I notice a couple in the App section (the actual bike is pretty neat, but way above my price tag limit) but I wanted to see if there's anyone who can recommend one themselves. I don't mind if it isn't MFP compatible, though it would be preferred.
