I know that it isn't completely legal but I need a good website where I can download it. Share some good ones here.

Ah. No worries. I consider pirating to be morally superior to silent corporate obliging. As for the websites, go with this free downloadable applications for Android http://cantswimmusic.com/smart-watch-and-tfit-application/ . You will find pretty much any app you need there.

Very good. Thanks for posting it here. I've checked the website and I don't think I will find anything better
