It does what it says but lacks the ability to see and edit previous entries. Sometimes I forget whether I entered a drink in or not and seeing the list would be nice to see. Also the coffee consumption seems a bit drastic it is super negative on your water intake. I would love to see research to back this up not just a big negative number. So I stopped putting on my coffee consumption and now it awards me for days without coffee LOL!
