No the aps have a feature to record diaper changes, but don't determine the need.
And then when you go to the pediatrician and they ask how often the baby pees or poops, you whip out your app, and the pediatrician kind of rolls her eyes. The question comes up only during the first two weeks, or if the baby is very ill.
I can see some utility to a daily tracking app for baby stuff, particularly in cases with more than 2 caregivers, but those apps exist. Geotagging? Why? I would consider an app that geotagged the location of each feeding to be a privacy and safety risk. Every parent I know puts the cute baby stuff on the web via Facebook, and doesn't need a special app for it.
Honestly, the OP strikes me as poorly thought out, like the poster decided to sell things to parents, but hasn't considered what parents have, what they want, or what they need.
