About this app

Ready for a lifestyle that prioritizes health and wellness?
Ready for living with more energy and focus?
Keen to have better sleep, improve mood and body composition?
How about balancing your hormones naturally?

The answer? Do your daily activities at the optimal time for your body.
Anchor your life to sunrise and sunset to optimize your circadian rhythm.

▌Circadian rhythm, biorhythms & chronobiology: the science🔬

Your body's circadian rhythms are 24-hour cycles of biological, hormonal, and behavioural patterns. This biorhythm modulates a wide array of physiological processes, including your hormones (i.e. melatonin), sleep, hunger, and metabolism, ultimately regulating body weight, performance, mood and susceptibility to disease. As such, your circadian rhythm has profound implications for well-being and longevity.

The 2017 Nobel prize in Medicine was given for research on circadian rhythms. Circadian clocks in almost all of your cells govern cellular functioning. When you disrupt your circadian clocks, chaos, inflammation, and disease are consequences.

Circadian is your app for applying circadian rhythms and living more naturally. Circadian uses local times (i.e. sunrise and sunset) plus user settings to calculate your circadian rhythm, also known as biorhythm. Optimize light, exercise and food timing to finally live better. Harmonize your life with the natural cycles, and let yourself be surprised!

▌Set reminders & alarms for critical circadian events to live well 🔔
In line with natural cycles, like light & dark and seasonal changes, Circadian provides reminders & alarms to operate on your optimal biorhythm. Start syncing your sleep cycle with nature and be active when you are meant to. Use Circadian as a daily schedule to live well. Set reminders for:
○ daybreak, sunrise, solar noon, sunset and nightfall
○ ultraviolet light rise and fall (UVA and UVB)
○ sleep and wake times
○ natural eating and fasting
○ morning and peak exercise
○ peak cognition

▌Adjust your sleep with the seasons💤
Your biorhythms govern daily functioning, while seasonal rhythms affect longer-term behavioural & metabolic changes. Circadian adjusts your sleep duration dynamically based on your location. Let your biorhythm become the schedule that keeps you in sync with natural cycles, balances hormones (ie cortisol & melatonin), and leads to better sleep. Your internal natural cycles & hormonal ebb & tides will be harmonized as a by-product.

▌Include fasting in your daily schedule 🍴
Eating and fasting are important cues for your biorhythms. Aligning your eating time with circadian rhythms is essential to balancing hormones, lowering inflammation, preventing/reversing disease and better sleep.

▌Understand and learn with Circadian 💡
Why is daylight (via UVA light) the first step to make melatonin?
Why is sunshine essential for your hormonal balance and health?
Why is an indoor lifestyle an on-switch for stress hormones?
Find these and many other answers with Circadian!
The learn section provides carefully curated in-depth content, practical suggestions & many surprises.
Learn about circadian rhythm, light (sunlight, UVA, UVB, red/infrared & artificial light), melatonin, sleep, grounding & much more.

▌Still doubtful? ☝️
Consider that circadian disruptions are linked to almost every modern disease, from diabetes to cancer. Don't believe it? Search: "shift work" or "circadian rhythm" plus a disease name.

▌What does Circadian cost? 💵
Circadian offers a 7-day free trial + a limited free version after that. Prices for the full version vary based on the country/region.
