Daily Energy Cycles

The energy level hints at the main Endel screen mark the current phase of biological rest-activity, and sleep-wake cycles — or ultradian and circadian rhythms. The phases change every 20 minutes, going through highs and lows wave-like, and forming a daily cycle, universal for life on Earth.

Once you harmonize your periods of high and low activity with this cycle, your daily productivity and wellbeing boost. See where you are on the scheme below — and choose accordingly: both your next move and a matching Endel soundscape.
 

This is a basic 24-hours model of a perfectly productive day, as suggested by studies of the biological rhythms. Everyone certainly has individualities and externalities that will shift this pattern. Soon we’ll personalize this daily energy curve for every Endel user.

Ultradian rhythm is a rest-activity cycle that regulates cognitive state, mood, and energy level. It consists of 110-minute loops of the energy’s up and down phases.

Circadian rhythm is a sleep-wake cycle that regulates the secretion of a ‘sleep’ hormone called melatonin. This process is constantly fine-tuned with natural light level.

Endel uses these universal rhythms as a baseline for sound personalization.

Adaptive Soundscapes

Endel soundscapes help to compensate for any disruption day and night, realign your mind and body with predefined biological rhythms, and, as a result, — they help you cope with daily challenges.

Relax
Calms your mind and creates a feeling of comfort with soothing sound textures

Focus
Helps you concentrate on tasks and keeps you in the flow with percussions purposely harmonized with the heartbeat

Sleep
Soothes you into sleep and gives a good rest with delta waves modulating noise

On-the-Go
Promotes physical activities of all kinds

Personal Inputs 

Personal inputs — heart rate, weather, motion type, and natural light — are essential for Endel to realign your current state with the circadian and ultradian rhythms. This is made possible by an adaptive soundscape.

The input that currently matters most is shown in the app below the circadian/ultradian phase.

Natural light
Light makes the biggest difference for the circadian rhythm. Even when you are not exposed to it directly, your body feels any change in light conditions. Endel tracks the natural light level and compensates for the lack (or excess) of it by adapting the soundscape’s intensity.

Heart rate
Endel adjusts the beat to your resting heart rate by comparing it to your real-time heart rate from the Health (iOS) or Google Fit (Android) app.

Weather
Endel reacts to the outdoor temperature with variations in sound layers.

Motion type
Endel alters sound intensity according to the number of steps taken per minute.

Sound Personalization

Endel’s sound engine consists of sound layers, modulations, and effects — all created in line with psychoacoustic studies. An algorithm processes user-state information and generates a soundscape accordingly — by constructing unique combinations of sound engine components.

Soundscapes adjust automatically through the day and fine-tune by user-state inputs — to provide the right sound intensity at any phase of the biological rhythms.

How Endel Works

The Circadian Rhythm

The base input for Endel is the circadian rhythm: the internal biological clock that regulates the body’s sleep and wake cycles — as well as natural energy peaks and slumps — over a 24-hour period.

However, the circadian rhythm can get disrupted by the surrounding environment.

24-Hour Cycle

User State

The surrounding environment affects the body throughout the day and can make the circadian rhythm out of sync. Personal inputs (time zone, natural light, heart rate, motion type) are essential for Endel to realign a user's current state with the circadian rhythm. It is made possible by an adaptive soundscape.

The resulting soundscape adapts to inputs in real-time. The input that currently matters most is shown in the app below the circadian phase.

Natural light
Endel compensates for the lack (or excess) of light outside by adapting the soundscape's intensity.

Heart rate
Endel adjusts the beat to your real-time heart rate, borrowing it from the Health (Google Fit) app and comparing it with your normal resting HR.

Weather
Endel reacts to the outdoor temperature with variations in sound.

Motion type
Endel alters sound intensity according to the number of steps taken per minute during your walking session. 

3-Hour Change

Sound Engine

Endel’s sound engine consists of sound layers, modulations, and effects — all created in line with psychoacoustic studies. An algorithm processes user state information and generates a soundscape accordingly — by constructing unique combinations of sound engine components.

This happens on the fly, reacts to changes, and allows Endel to sync a user state with the circadian rhythm.

How Endel Works

Daily Energy Cycles

You should notice energy level hints at the main Endel screen, marking the current phase of biological rest-activity, and sleep-wake cycles — typically known as ultradian and circadian rhythms. Phases change every 20 minutes, with varying highs and lows that form a daily cycle. This variation is universal to life on Earth.

Harmonizing your periods of high and low activity with this cycle is a natural way to boost your daily productivity and wellbeing. See where you are on the chart below and choose your next move accordingly, then pick a matching Endel soundscape.

 

This is a basic 24-hours model of a perfectly productive day, as suggested by studies of human biological rhythms. Everyone is unique and deals with their own unique stresses, which shift this pattern. Our goal is to personalize this daily energy curve for every Endel user.

Ultradian rhythm is a rest-activity cycle that regulates cognitive state, mood, and energy level. It consists of roughly 110-minute loops of the energy’s up and down phases.

Circadian rhythm is a sleep-wake cycle that regulates the secretion of a sleep hormone called melatonin. It repeats every 24 hours and is constantly fine-tuned through natural light level.

Endel uses these universal rhythms as a baseline for sound personalization.

Personal Inputs 

Personal inputs — heart rate, weather, motion type, and natural light — allow Endel to help you realign with the circadian and ultradian rhythms. This is made possible through an adaptive soundscape.

The most important input for the soundscape playing is shown in-app below the circadian/ultradian phase.

Natural light
Light has the biggest impact on the circadian rhythm. Even if you aren't exposed to it directly, your body is sensitive to changes in light conditions. Endel tracks natural light level and compensates by adapting your soundscape, changing sound intensity to maximize your comfort level.

Heart rate
Endel adjusts the beat to your resting heart rate by comparing it to your real-time heart rate using data from the Health (iOS) or Google Fit (Android) app.

Weather
Endel reacts to the outdoor temperature with variations in sound layers.

Motion type
Endel alters sound intensity according to the number of steps taken per minute.

Sound Personalization

Endel’s sound engine — Endel Pacific — consists of sound layers, modulations, and effects — all created in line with psychoacoustic studies. An algorithm processes user-state information and generates an appropriate soundscape by constructing unique combinations of Endel Pacific's components.

Soundscapes adjust automatically throughout the day and adapt based on user-state inputs — to provide the right sound intensity at any phase of the biological rhythms.

Real-time inputs tell Endel about your current state, environment, and natural energy cycle – known as the circadian rhythm. This allows Endel to create soundscapes that are uniquely personal, and optimal, for you.

Natural light

Endel sees your outdoor natural light level from your location and compensates by adapting sound intensity to better match your body's circadian rhythm.

Heart rate

Endel adjusts soundscape tempos to your resting heart rate. When your heart rate becomes significantly higher or lower, Endel adapts the soundscape to help you realign.

Wake Up Time

Based on your most recent wake-up time, Endel uses this to make your circadian phases more accurate and personal. 

Weather

Depending on whether it’s cloudy, sunny, or rainy outside, Endel reacts with personal sound layers.

Activity level

Activity-themed soundscapes react in real-time to your steps-per-minute, changing the intensity and complexity.
