Endel
Endel generates personalized, science-backed soundscapes that adapt in real time to your heart rate, mov ement, time of day, and local weather. Offers dedicated modes for focus, relaxation, and sleep. Available on iOS, Android, an d web.
Binaural beats may not be suitable for people with epilepsy or pacemakers.
What is Endel?
Important: Endel uses binaural beats (specific frequency patterns played differently in each ear) in some soundscapes. These may not be suitable for individuals with epilepsy, seizure disorders, or those wearing cardiac pacemakers. Consult a healthcare professional before use if you have any of these conditions.
Endel is a soundscape application available on iOS, Android, web, and Alexa-enabled devices. It gen erates continuous, algorithm-driven audio environments that adapt in real time to multiple input signals: the user's heart ra te (via Apple Watch or other connected wearables), movement and activity level, time of day, circadian rhythm phase, and loca l weather conditions. The app offers four primary modes — Focus, Relaxation, Sleep, and On-the-Go — each designed to align th e soundscape's tempo, frequency, and texture with the intended activity. Endel's approach is grounded in psychoacoustic resea rch on how sound frequency and rhythm affect the nervous system, including the use of binaural beats to support concentration and sleep onset. Users can start a session manually, let the app auto-select a mode based on the time of day, or set timed pr esets for specific routines. The free tier includes access to Focus, Relaxation, and Sleep modes with standard soundscapes; t he premium tier unlocks full biometric adaptation, the On-the-Go mode, Alexa integration, Apple Watch companion, and the comp lete soundscape library.
