Snake Rules — Precise measurements from a single photo
Snake Rules makes it easy to measure the length of snakes, lizards, and other animals using just a photo and a simple reference object. Whether you are a keeper, breeder, or enthusiast, you can obtain accurate measurements in seconds — all directly on your device and without collecting any personal data.
How it works
Take a top-down photo of your animal next to a reference object
(a ruler, tape measure, phone, bank card, etc.).
Mark the start and end of the reference object to set the scale.
Add points along the animal’s body for precise measurement.
Adjust points by dragging them for maximum accuracy.
Save your results and organize them by individual animals.
Everything happens on-device, securely and privately.
