I see you have a bottle default
Make other bottle and or glass size defaults.
Maybe the person has a big plastic bottle they carry around, or they buy small bottled waters.

Custom should only be if they dont fall into your defaults

Put them in a drop down menu or something

there's no contrast between your icons so increase that a bit.
Make it send notifications to you to remind you to drink.
Make it congradulate the user for drinking so they feel good for drinking all the water in a day
Track thier progress per day to get them to meet goals

"You have drunk : 1500" or "You drank : 1500".
And in this iteration of your thread you have introduced the word "Menue" to the English language. We use the phrase "Bill of Fare" to avoid propagating the French influence "Menu" in English. Also the gui advice suggested by other anons.

You should add a function which reminds you to breathe.

Might seem like a no brainer, but fitbit/samsung watch/etc functionality.

Also, if you want to want to be like every asshole dev out there, charge a small amount to save custom sizes. Like a buck. I'm assuming you're doing free with ads.

A pedometer function would be nice as well, or gps distance tracker for jogger and cyclist bros an broettes.

My company uses an app that reminds people to stand up and walk around once an hour because we sit at our desks so much. So, yeah, it's definitely is a thing. That said, it took one guy 2 hours to program it and it's free so don't expect to make any money off of it. Especially considering we don't actually know how much water a person should drink a day. The whole 8, 8 oz. glasses thing has no basis in science.
