This is a heuristic based on age and today's log — a guide, never medical advice. Your baby didn't read the chart, and that's fine.

Your baby's data goes nowhere. No account, no cloud, no ads, and zero third-party trackers — this page doesn't talk to Google, Facebook, or anyone else. Everything lives on this device, export is free forever, and erasing really erases.
ESPOnest is a logging tool, not a medical device, and its estimates are not medical advice. For anything health-related, call your pediatrician.
