It’s pretty easy to use, but is terrible for synching data with a partner or spouse, or other caregiver. You have to manually send the data from one phone or device to another, and in the middle of the night, or when you have a lot going on, is a real/absolute pain. And data goes missing if one person records on one phone but the other’s phone was more up to date. Too many headaches when you’re just trying to make sure your kid is eating enough and peeing/pooping enough. We also noticed that all of the data we had recorded since birth had been duplicated multiple times, likely because of the Transfer Data option over email having a glitch (pretty sure we were doing it right!). So now we are exporting our data and using the other Baby Tracker app from now on, which syncs in real time using a group. Wish we had started with that one! Don’t make the same mistake as us! Looks like the paid option also lets you use Siri and Apple Watch (Hello hands free! Huge help!).
