I like Apple Watch very much! I always run 6k with Apple Watch, after run I always want Poop , I just consider use Apple Watch record my Poop pace ,frequency and also have some reports. I feel that is a good thing. I'm the developer, so I just write one and put on App Store. Hope you guys also like it. it is the world first app to support the recording of poo-poo on the watch and it is completely independent. In App Store, search "GoPoop" you can download and install, add this healthy function to your apple watch!
