Im exclusively pumping, I have used this app for a week and love it. There is one flaw and a few modifications that Im wishing for). If you make a mistake and input it as one container when you fix it the original container is still maintained with the combined volume... I correct this by dumping the error amount (which obviously isnt right but Im not fussed because I dont track dumped milk - which in my case is none) There are three modifications that I would wish for - 1 history - I wish you can just toggle between seeing feeding only or pumping only instead of both. I want to see the fluctuations between pumping session volume and feeding volume per feeding. Another is the supply #. 2 - I wish there was a bar chart per day that shows you how much your stash is growing. Ive been tracking for a week and Im now at 2 day stash with 1.5 freezer and .5 fridge would love to see how much each stash is growing by day. Right now I have to go to statistics to see it for that day. 3 - I use the small 80 ml bottles and sometimes I use more than 2 containers - so I have to create a fake pump so that the containers can be I putted properly. Wish you can divide up the pumping session in more than 2 containers. This is my very first review of any app so its obvious that I use this app enough. Also, I started out formula feeding and had to create earlier fake pump session so I can track the feeding amount in the beginning, cant the app have a button for formula feedings for those mothers that supplement?
