Calipo by Sazka estimates your body-fat percentage from a few simple tape measurements using the widely used US-Navy method, giving you a repeatable number to track over time instead of guessing from the mirror. Measure your waist, neck and height in centimetres, enter them, and Calipo by Sazka returns an estimated body-fat percentage along with the category it falls in.
The categories screen lays out the usual ranges — from essential and athletic through fitness, average and above — so your result always arrives with the context to understand it. Everything is built for quick input and large, readable output, and your last entry is remembered so tracking week to week takes seconds.
There are no accounts, no sign-ups and no clutter. Tape estimates are approximate and this particular formula is intended for adult men; it is a general fitness guide, not a clinical body-composition measurement or medical advice. For anything that matters, talk to a qualified professional.
