• Best Use Tips
    • Endel soundscapes are not music
      Rather than consciously listening, immerse yourself and let Endel be a protective bubble.

    • The minimum effective time is 15 minutes
      Set a moderate volume level and use headphones or wireless speakers when possible.

    • Regularity is more important than duration

  • How Endel Works

    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.

    CiracadianRhythm-Illustrated-Modes.svg

    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 


    CiracadianRhythm-Illustrated-BiologicalRhythm-02.svg

    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


    CiracadianRhythm-Illustrated-Sound.svg

    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

    CircadianRhythms.png

    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.

    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.
