In a recently completed walking activity, I saw moisture loss and wondered if I could add what I drank during the activity. Sure enough, under edit and then show more data, there it was. It takes forever to enter though.
The units are in ml, and the input method is scrolling. It's not rounded to the nearest 50 or even 10, I guess for some people it matters that it was 493ml consumed and not 490 or 500.
It takes a ridiculous amount of time to add that you drank 500ml, one of the most common sizes of bottled water around here.
Why not change it to a simple input field, perhaps even with some shortcut buttons like the regular hydration tracking?
