It’s ok
It gives me a notification which is what I need but it’s the same notification sound as everything else and I can change it so I miss it. I like that it has a watch app but logging on the watch doesn’t work most of the time. I have a 16oz bottle and when I drink it all and “refill” it on the app, it says I have 0 left to drink today despite that being 16oz out of 120oz. Also, it required me to write a review in order to use the history function. I will continue to use it but I’m not that impressed.
