Nox

Nox is a sleep habit app that doesn't track you. No wearables. No microphone. No sensors. Just two honest questions — how long did you sleep, and how focused did you feel today? Log your hours and your focus from 1 to 10. Over time, Nox identifies which nights gave you your best days and uses them to calculate your ideal sleep duration, bedtime, and wake time. The math is simple by design: average the sleep from your highest-focus nights. No black box. No algorithm you can't explain. Just your own data, reflected back at you. Once enough qualifying nights are in, Nox shows you a live countdown to your personal bedtime — not a generic recommendation, but the window your own history suggests. Flag unusual nights so they don't skew your pattern. Review your full observation log. Adjust your schedule when life changes. No ads. No subscription. No cloud sync. Everything stays on your device. Your ideal night is already in the data. Nox just finds it.
