About

Helio

Read full description

Most circadian rhythm advice assumes you live in one place, in one time zone, with a fixed routine. Helio doesn't. Built for digital nomads, frequent travelers, and anyone whose schedule doesn't follow a 9-to-5, Helio calculates your exact local sunrise and sunset using your GPS location. Then it tells you precisely when to get morning light, catch the afternoon sun, cut off caffeine, and start winding down. No fixed clock times. No generic advice. Just your actual solar schedule, recalculated automatically every time you change location. Why solar time, not clock time? Your circadian rhythm doesn't care what time zone you're in. It responds to light. A "get sunlight by 8am" rule means nothing if you just flew from Bangkok to Lisbon. Helio anchors every recommendation to the sun itself, so your schedule adapts the moment you do. What Helio tells you, every day: - Morning sunlight: when to get outside to anchor your circadian clock and trigger your natural cortisol rhythm - Afternoon sunlight: a second light exposure window that locks in your evening wind-down timing - Caffeine cutoff: calculated backward from your ideal sleep time, based on caffeine's actual half-life - Dim the lights: when to start reducing light exposure so melatonin can rise naturally Built with travelers in mind: Schedule recalculates automatically when you change location or time zone Gentle, optional daily reminders, never more than one per cue Clean, fast, no clutter Your privacy, respected: Helio uses your location only to calculate sunrise and sunset. It is never stored, never shared, never sold. No account required. No ads. Backed by the biology, explained simply: Every cue includes a short, clear explanation of the science behind it, because understanding why matters as much as knowing when. Whether you're chasing the perfect jet lag recovery, trying to build a sustainable routine while living out of a backpack, or simply want to understand your own body's rhythm a little better, Helio gives you a schedule that travels as well as you do.
