Didn’t know it would be so helpful


Something like this is not necessary, but it’s so incredibly helpful! My wife and I both use it to track her daily sleeping, eating, and voiding primarily but logging baths, growth points, injuries, photo and text diary entries, and exactly what she eats is so easy. When I go to the pediatrician I have lots of good quantified information. The new feeding log display option menu is in Japanese characters so I can’t tell what it lists but I love the app just the way it is. Thank you!!

Loving it


So far this app is really great. The icons make it easy to know what you’re recording and the layout takes just a quick glance to notice patterns and trends. The ability to add a daily photo and diary is really cute and I know I’ll be looking back on all of this. I really love it, and it’s shareable!!
