Is there an Apple Watch app? Yes, there is an apple watch app that will sync with the app on your phone, and you can even manually add water from the watch if you want. Have more questions? Submit a request 4 Comments Date Votes 0 Danielle Cohen June 22, 2016 11:53 Will you be making an app for any other smart watches? 1 Cammy Ann Hell January 31, 2017 14:17 Apple Watch app doesn't work. It just says. Log in. Idk what that means considering I'm already logged in on my phone and there's no way to log in on the watch. What do I do? 0 Rick Morgan March 13, 2017 02:19 I have the same problem Cammy, but not all of the time. Sometimes it works and i can see my amount of water consumed and can add some to that volume. Other times it just says "Log in" smh. 0 Nikki Snier July 21, 2017 00:28 The app on my Apple Watch isn't working at all. All that comes up is the water icon. Will this be updated soon?
