LittleObserver
Nature Discovery Journal
Free · Designed for iPad. Not verified for macOS.
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.
