Walk to get fit

[smolbear]

Has anyone tried WalkFit? And is it worth the money?

I have not paid for anything to do this apart from I got a smart watch. I just put in headphones and walk and set myself a goal of how far/time and try to beat myself in how long it takes me to walk a mile. I had a look at the app - a lot of this data is accessible via my iPhone app with my watch anyway, apart from specific programmes they are promoting. How expensive is it?
