About

Endel is an app and multi-platform service that creates personalized, generative soundscapes designed to help listeners concentrate, unwind, fall asleep, or stay grounded during physical activity. Unlike static playlists or looping ambient tracks, Endel's patented technology generates audio continuously and adjusts it in real time based on inputs such as time of day, local weather, heart rate, and location. The company says its approach is grounded in neuroscience, citing a whitepaper on bioRxiv and survey-based research reporting improved focus and reduced stress among regular users.

Endel is available across a wide range of devices, including iOS and Android phones, Apple Watch, Amazon Alexa, Apple TV, Fire TV, Mac desktop, and a browser-based web player, with additional albums and playlists on major streaming platforms. The app has been downloaded more than 4 million times and has received industry recognition, including Apple Watch App of the Year 2020, App Store Editors' Choice, and Google Play Best of 2021.

Key Features

Adaptive real-time soundscapes: Endel generates sound continuously rather than repeating tracks, and adjusts the audio to contextual inputs like heart rate, light, weather, time of day, and location.

Four core modes: Focus aims to support longer concentration, Relax calms the mind, Sleep uses soft sounds to ease the transition into deep sleep, and Activity pairs audio with movement.

Apple Watch app: A standalone wearable version that works without an iPhone nearby, using the watch's heart rate and other biometric sensors for more detailed personalization. It won Apple Watch App of the Year 2020.

Alexa integration: Soundscapes are available on Echo devices, Fire tablets, Fire TV, and Alexa Auto with no installation — a phrase like "Alexa, start Endel" begins playback, and Alexa Routines can automate sounds around sleep and bedtime.

Autoplay: The mobile app can automatically select the appropriate soundscape for the user's current state throughout the day, from morning work sessions to evening wind-down.

Desktop and web apps: Endel for Mac offers a streamlined interface designed to reduce distraction, and a browser-based web player streams real-time generated soundscapes with matching visuals.

Streaming releases: Albums, singles, and playlists created with Endel's technology — including collaborations with artists such as James Blake and Ta-ku — are available on streaming platforms, though these versions are not adaptive.

Who It's For

Endel is aimed at people who want background audio that responds to their circumstances rather than repeating a fixed playlist. Remote workers and students use the Focus mode for deep-work sessions, while light sleepers and people with insomnia use Sleep sounds at night. The company also highlights ADHD support as a common use case, and the Activity mode suits runners and others who want grounding audio during movement. Households with Alexa speakers or an Apple TV can use Endel for screen-free sleep and wind-down routines.
