Alarm to remind me to drink more water

I have a special alarm that I use to help me drink as well; I place it on the cup and it alarms every 15 minutes and that helps to remind me to drink. I don’t know how to explain it but sometimes you just have to do and get these in to to live better and not end up in hospital because you’re dehydrated and confused, which I have a fear of really.
