Simply the best running app, if you're into customization and like to analyze a lot of data. There's no app which allows to create your own pages with metrics and diagrams, not only for the iPhone but also for the Apple watch. The Elite subscription is a no brainer as you get so many valuable features for a good price. Looking at the free version, I think there are better options in the App Store but the Elite version is unmatched. The only thing I regret is that it requires you to take your iPhone with you, although the Apple Watch 2 doesn't require this, with build in GPS. Although I believe it's wise to take your iPhone in case of emergency, support for Apple watch 2 would make it a 5 star rating. Keep up the good work!
