Tracking and stats are great but have a silly convoluted system to login in from different devices via iCloud sharing. That's fine for my multiple devices but now my wife can't login. She has to input data via a shared note and then I have to enter into app. What a waste of time? So easy to build password protected login like every other app on the planet. I've already input all data since the moment my daughter was born 12 days ago so I am loathe to start something new and export data. Have more important things to focus on at this time. But we are just tracking until 2 week pediatrician appointment and then I'll dump this app in search of better options.
