Hate the new update to the feeding tracker. It used to be detailed and large right when you open the app. Now I've got to click through 1600 steps to see when I last fed baby and on what breast and how long. It's an absolute pain. Bring back the old version! The new one is so obnoxious with huge icons and super tiny print. Part of why I loved it before was because I could see everything I needed to know with a glance right away. Not worth it to track diapers

Tracks how many weeks and days you are as well as gives an example object to compare it to (that you can change the theme of, which is really cool, like knowing your baby is the size of a Willy Wonka Chocolate bar bahah). Also gives a bunch of helpful articles to read. Lists common symptoms that typically occur during your progress. It's overall simple to use and helpful! :)

Overall good, Useful app. Needs a dark mode though! It's too bright for use in the middle of the night when I need to turn it on to track breastfeeding. Otherwise it's been super helpful. Also, it could really use some updates to how you can adjust times and whatnot. Annoying that you can adjust anything until you save once first
