I’m surprised this isn’t a bit higher rated tbh. Ads are always annoying but it’s a free app&am able to close them out&log my drink,I have no issue using Drinkwater. It has a good selection of drinks,you’re able to set up notifications(I leave myself a nice message,you can write whatever you want),get as many or little notifications as you want,I don’t drink but like that it has alcoholic drinks so you can see how it dehydrated you,I also like that it has what other apps I’ve come across don’t which is how much you actually absorb so you can have a 12oz glass of something but will only count 10oz because that’s how much you actually get(not that I know if it’s accurate or not) of course plain water you get the full amount. This is the only free app I’ve come across that is actually free,every other app you have to pay to unlock majority of drinks. I also like that it takes your gender,age,weight into consideration&you can also change your goal if you want to however I don’t see an option for activity level which I would like because I’m sure an athlete&someone sedentary would be different.
