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.

Ratings and reviews

This is a great app if you are looking to align certain activities to daylight over the course of the year. They have also done a good job updating the app to resolve prior issues. When I had a problem with my subscription they responded quickly and rolled out an update to fix it. This is the best app I've found with adjustable sunrise/sunset alarm functionality.

This app is beautiful and highly useful. Bringing our lives into alignment with circadian rhythms requires a significant lifestyle adjustment. Most of the world today lives completely tone deaf to the natural cycles. This app is a tremendous tool for bringing your life back into rhythm. I had some initial technical problems with the app and subscription, but all is straightened out. The team was responsive and figured out what was wrong.

I like a lot of what this app does, so I bought a lifetime license.... But, it seems to be missing a major feature which is to be able to best schedule a nap based on circadian cycles. It would also be really great to have a connection to smartwatch sensors to help adjust settings, based on how the body is responding.

What's new

This version connects with a new backend, enabling faster and improved connection to locations and all learning content.
