Scaley

Stop being fooled by your scale.

Your weight fluctuates 1-3 kg every single day. Water retention, meals, time of day — all of it adds noise that hides your real progress. Scaley uses Bayesian statistical modeling to cut through the
noise and show you what your weight actually is.

How Scaley is different:
Weigh yourself any time — morning, evening, after lunch — it doesn't matter. Scaley learns your body's daily pattern and automatically adjusts for time-of-day fluctuations. You get one clean number:
your estimated true weight, with a confidence interval.
