Description
Take your health into your own hands. Sync to circadian rhythms and give yourself the edge. Sleep, wake, eat, exercise and think at the optimal time for your body.
Ready for a lifestyle that prioritises your health and wellbeing?
Ready for living with more energy and focus?
Keen to naturally improve mood, body composition and sleep?
The answer? Do your daily activities at the optimal time for your body - aka circadian rhythms or the power of 'when'. ⏰
Enter Circadian, your app for applying circadian rhythms, and living a more natural lifestyle. Circadian uses your local solar time and some user settings to calculate your circadian rhythms, also known as biorhythm.
◾ Set reminders and alarms for critical circadian events
Being a biorhythm calculator, Circadian provides you with reminders & alarms to operate on your optimal biological schedule. Start sleeping, waking, eating, fasting, exercising and working when you are meant to. Set reminders or alarms for
- solar times (daybreak, sunrise, solar noon, sunset, nightfall)
- ultraviolet light rise and fall (UVA/UVB)
- sleep and wake times as well as a digital sunset
- eating and fasting times as well as meal timings
- morning and peak exercise times
- peak cognition times
◾ Adjust your sleep with the seasons
Circadian rhythms govern daily functioning, whereas seasonal rhythms, also referred to as infradian rhythms, affect longer-term behavioural and metabolic changes. Circadian can adjust your sleep duration dynamically based on the changing light conditions at your location. This keeps your bodies biorhythm in sync with seasonal changes.
◾ Feast and fast in line with natures pulse
Optimise your eating times and upgrade your intermittent fasting routine to a whole new level. Eating and fasting in sync with circadian and ultradian rhythms (less than a day) is essential if you want to reverse a metabolic disease or avoid getting one in the first place.
◾ Learn and implement with Circadian
The learn section provides you with carefully curated content on all things circadian rhythm related. Circadian is the most science-backed lifestyle app yet gives you the needed context fast.

- Take action with our suite of practical suggestions
- Browse the best products to support your biorhythm
- Rest easy knowing that all content is based on more than 1000 scientific references
◾ The science behind circadian rhythms (chronobiology)
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, sleep, hunger, and metabolism, ultimately regulating body weight, performance, mood and susceptibility to disease. As such, circadian rhythmicity has profound implications for your wellbeing and longevity.
The 2017 Nobel price 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 the natural consequence.
Artificial light or "junk light" is the main culprit for circadian disruptions. Which is why more natural light exposure, especially at sunrise and sunset, is crucial to reset and tune your biorhythm. Learn more in the app.
◾ Still doubtful?
Consider that circadian disruptions, and the ensuing inflammation, are linked to almost every modern disease from diabetes to cancer. Don't believe it? Search: "shift work" or "circadian rhythm" plus the name of a disease.
