Water bar in oz.

I would love to see my water bar progress in oz. I can do the conversion. I get why the option is there for the weight of the water. My goal is more simplistic in that I just want to track my water. Even in mL or L would be fine. I just want to look at it and determine quickly where I’m at. I swear, there is no one app that has it all. I thought this was the one. I literally just want to track the amount of water I’m drinking quickly and simply.
