Buggy on Apple Watch. Drink water reminder app is better – Daily Water - Drink Reminder Review

I just got a used Apple Watch v1 with WatchOS 3 and on iOS 10. This app has nicer UI. Clicking on a cup is easy. However, the app keeps stalling and crashing on my Apple Watch and causes battery drain. So I tried the "drink water reminder" app. It's not as pretty and it's a bit annoying to wait for the oz to countdown slowly when tapping that you drank a cup, but at least it works flawlessly on my watch and iPhone.
