thank you so much Marianne! Yes, it was actually about 25 altogether (15 walking and 10 skating). All of your activities count..its a matter of what you are willing to focus on to get your activity up. I haven't interacted with the ios version personally, but when I am in the actifit app it has aeorbics prefilled, when I touch that spot a list comes up that I can check off my activities (you can choose as many as are applicable). I am thinking it should be similar <333
