User friendly 👍🏾

This is simple and very user friendly. You can add water in basically any size with the custom tab (conveniently located right next to the preset amounts) you can adjust the notification times too. I am accomplishing my water goal so much easier with this app. It's fun to hear the water bubbling sound!

It can add some feature that make this the perfect app

So first thing I want to say is that instead of having a fix amount of oz to choose from, I would like it if we can scroll the crown on our Apple watches to adjust the amount of oz we would like to put. For example , if I can change it to 10 oz or 27 oz but those measurement are not in the app or the Apple watches. And the second thing I would like this app to add is that instead of just having the reminder set to hours, I would like it if you can also use minutes because when I tested the other apps, I like to set my reminder to every 30 minutes to remind me to drink. If you add those two features, I would say this is the best water reminder app I would ever use and I would rate it a five star instead of a three.

Best one I’ve found

This is the best water app I’ve found. I like the way it’s set up and that it works with my watch. My only problem with it is, I wish you could change the water amounts listed in the settings. I drink 10.6 ounces every hour for 12 hours, drinking a gallon of water a day. On other apps I was able to just click 10 oz and it would save it (close enough) I know I can type it on each time but it’s almost a hassle and I can’t do 10 oz on the watch at all... so if we were able to change the amounts listed in settings it would be absolutely perfect! Other than that, it’s great for now
