Good but not great
If you are about to deliver or are looking at this because you are overwhelmed at the hospital just after delivery, spend a few bucks and buy "milk monitor". It lets you pause (necessary if your baby takes a while to latch or goes on and off) and it lets you monitor diapers, medicine and add notes. All can be edited, notes can be added, and you get a chronological list for everything. No graphs though.
