LittleObserver vs Triangle Sketch

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.

Triangle Sketch is a hands-on geometry tool for drawing and exploring triangles. Draw a triangle with your finger, check its measurements, edit side lengths and angles, move vertices, enter coordinates, and view useful triangle facts. Triangle Sketch helps students see how triangle measurements connect instead of only reading formulas. Features: • Draw triangles directly on a graph • Edit side lengths, angles, and vertex coordinates • Work with any triangles and right triangles • View area, perimeter, triangle type, height, centroid, incircle, and circumcircle • Use right-triangle trig tools • Change units, decimals, colors, grid snapping, and display options • One-time hints help students discover important tools Triangle Sketch is designed for students, teachers, and anyone learning geometry.
