6 Best iPhone Circadian Rhythm App
1. Circadian – Lifestyle Rhythm
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.
– Dive deep into the thoroughly researched content
– 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.

Our body contains circadian (circa – approximately and dian – day) or 24 h clocks that determines the time to sleep, feel hungry or get ready for physical activity. Research studies run in different locations are trying to understand the interaction between “how much” and “when” we sleep, eat or exercise for better health. You need an activation code from these research studies to download and use the app.
Following are the key features:
– Camera function to snap picture of everything you eat or drink
– Sleep tab to record time to bed and time of waking up

3. Rise: Sleep & Energy Tracker
Teams in the NFL, MLB, NBA, MLS as well as many Fortune 500 companies trust Rise to help members achieve better sleep.
FROM THE RISE COMMUNITY:
“Rise helped me understand how vital sleep truly is. In only a few weeks, I found myself more focused, energetic, and productive at work.”
“I could see where sleep debt was causing issues, like temper short, not comprehending things, moving slowly. I had an epiphany… I’m getting 45min more sleep on average than I was before Rise.”
“I never thought too much about the impact of sleep on my mood. With Rise I saw a very fast improvement in my sleep which impacted my relationship with my kiddos.”
Are you wondering how to get the most out of your sleep? It’s time to look beyond a new mattress or getting eight hours of shut eye and focus instead on your SLEEP DEBT.
Sleep Debt is one of the most vital findings in the last century of sleep science. When your Sleep Debt is low, your quality of life as well as your life expectancy increases. When your Sleep Debt is high, the opposite happens.
With Rise, learn what Sleep Debt is, how it works and then calculate your own. This will help you better understand why some days you feel great and others not as much. It will help you decipher when you should prioritize sleep and the real toll staying up late has on you.

We all have an internal brain clock that signals to your body when to be alert as well as when to go into recovery mode. Each body and mind is unique to another, from when we perform our best to when we should be sleeping and waking up. Given this individualization, we use advanced algorithms to highlight the optimal window for sleep and activity.
AUTOMATICALLY TRACK SLEEP
Through our integration with Apple Health, Fitbit, Oura, Garmin, Sleep Cycle and data from other sleep trackers already on your phone, Rise can determine the hours of sleep you get every night, the number of steps you take each day, as well as data from other various activities that affect your sleep pattern.
WHY WE STARTED RISE
We want to help get ahead of the Insufficient Sleep Epidemic (CDC, 2014) we are currently experiencing and that has been steadily increasing since 1985. This Epidemic has led to elevated mortality rates (Cappuccio, 2010) as well as underperformance in most aspects of life (RAND, 2016).
Today, we look at sleep as a luxury. Rise strives to create a world where healthy sleep is a necessity.

“Humans have an internal biological clock that helps them anticipate and adapt to the regular rhythm of the day, namely circadian rhythm. Scientific research has shown the importance of circadian rhythm for human health, and led to a Nobel Prize in Physiology or Medicine in 2017.
Tempori is an innovative iPhone and Apple Watch app that helps users schedule some daily activities based on general circadian rhythms determined by daylight. It offers some timing related advices, and tracks suitability of activities at anytime, based on the user’s own schedule.
On iPhone, it lets the user set constrained schedules with intuitive gestures, and visualizes them as colorful arcs, together with a color-coded ring (clock) for daily variation of light conditions. Since light is the primary signal for circadian rhythm, the user can study the year-round daylight conditions at the current location interactively.
The watch app tracks the suitability of those activities continuously, based on the user’s schedule.
Tempori is integrated with the Apple Health app. In both iPhone and watch apps, the user can record health activities and save data into the Health app.
If the user subscribes to premium features, daylight conditions, daily temperature range and precipitation anywhere in the world can be studied, as well as hourly temperatures in US. Travel plans can be set on a map, and the watch app will help the user prepare for jet lag with automatic schedule shift before the trip. Personal activity data in the Health app will be visualized together with relevant schedules, for convenient comparison. These include sleep analysis, heart rates, dietary energy intake, caffeine intake, workouts, mindful sessions, toothbrushing, and handwashing events. The user’s historical heart rates and heart rate variability (HRV) are analyzed and visualized, to evaluate heart health and guide workout intensity. Sound levels and BMI are visualized. Correlated color temperature of light sources can be measured. Fish mercury level data are provided for dietary health. In addition, watch face complications offer gentle hints of the most important activity at anytime. If the user has not gone to bed after the scheduled bedtime, the watch app will try to notify the user based on activity detection.
In summary, Tempori takes advantage of and enhances Apple Watch’s essential function: timing. It will help users build habits for health and productivity.”
