This will be our second kid, and at least for us figuring out a name that we both love is hard. There are literally tons of baby-name apps out there, most of them more fully-featured and polished than Nom de Bébé and you should probably use one of those. However a lot of them include a disturbing amount of tracking or for any number of reasons just didn't work for my wife and I (bugs, subscriptions, lack of names, etc). So in continuing the tradition of "An app can be a home-cooked meal" [1], I built my own for us to use. You're welcome to use it too.
