Every one of these runs entirely in your browser. Nothing is uploaded, nothing is stored, there is no account and no email box. They exist because the same physiology sits behind Klivet — the difference is that the app watches it every day instead of when you remember to open a calculator.
The app
Klivet does this every morning, from your own watch data — and tells you before your body does.
