Lumo: Fasting Tracker

Lumo is a clean, focused intermittent fasting tracker that answers one question at a glance: am I fasting or eating, and how long is left? A clear ring counts down your window so you always know when to eat.

Built for the night — calm dark theme, turquoise fasting ring, amber accents.
