uGrow [1] by Philips is a similar app with another UX (I leave the better to others to judge). It has some options to connect with IoT devices for automated logging.

Disclaimer: sat next to the guys who made this at some point in time. Disclaimer 2: never used personally (though I have kids). As said before, you learn to relax. Tracking is too much hassle for me.
