I support this as an addition, but only as long as this doesn’t replace liters/ml.

Yes please! I don’t want to have to look up the conversion every time I enter my water intake!

Yes, this could include conversions for weight as well. Its not too challenging to remember that each tick of water is 8 oz though.

Would having it toggle between glass & bottle help anyone else? I tend to drink water from my bottle during the day it would be great to track that :)

Add as a system setting! Fluid ounces (vs mL), pounds (vs kg), feet+ inches (vs cm). Yes, the Americans are a pain. But having to calculate every time – you might as well be measuring your cups in cubic centimeters; it’s just not in anyone’s head

FYI, I found the pounds vs kg (thanks to a support article). It might actually be more useful to put unit switching in the places you enter them, since the setting was so well hidden.

I’d quite like flexible measurements of water, as a lot of my glasses of water are 300 or 400ml, which doesn’t fit neatly in the 250ml tick box.

I don’t know if this is workable on the app or if it would become too cluttered on screen, but I’ve recently started using my Garmin app & watch to track hydration. They have 3 customisable sizes of glasses, you choose what works best for you & then after you’ve take a drink you can click on the one closest to what you’ve drank, or click on one a few times to quickly add up to the amount you’ve drank. I find it quick & useful for me adding my hydration & keeping it accurate. It’s the first time I’ve stuck to tracking hydration because its easy.
