LittleObserver

A science journal for young naturalists — raise a creature, track its growth daily, and experience machine learning firsthand.

Little Observer turns creature-raising into a hands-on science project. Designed for elementary and middle school students, it makes biology observations easy, fun, and educational. HOW IT WORKS • Create a project for the creature you're raising — a caterpillar, snail, beetle, or any small animal • Take a daily photo and log its body length to build a real growth record • Use the built-in AI measurement tool: teach it by marking a few examples, and watch it learn to measure your creature automatically — a real introduction to machine learning • See your creature's growth change over time • Export the full record to Excel for class reports or science fair presentations GREAT FOR • Elementary and middle school science classes • Independent study and biology projects • Students who want to experience AI and machine learning through real-world observation No internet needed. Everything runs on your device.
