What is Endel?
Endel is an app that creates personalised soundscapes to help you focus, relax and sleep. Its website says the app has more than four million downloads and is backed by neuroscience research.
It works by generating audio in real time instead of playing fixed tracks. The sound shifts with inputs such as the time of day, the weather, your heart rate, your location and your walking pace. Because nothing is pre-recorded, a session can run for hours without repeating.
Key Features
Endel’s key features are four real-time soundscape modes, Focus, Relax, Sleep and Activity, that adapt to time of day, weather, heart rate and movement, with apps for phones, watches, computers, TVs and Alexa.
- Focus mode: Plays steady generated sound intended to support concentration during work or study. Endel promotes it as an alternative to playlists and cites its own research.
- Relax mode: Produces calming audio for breaks and winding down, which Endel describes as creating a feeling of comfort and safety.
- Sleep mode: Plays gentle soundscapes designed for falling asleep, and can run through the night because the audio is generated and does not loop.
- Activity mode: Sets rhythms that follow your movement, using the cadence of your walk as one of its inputs.
- Adaptive audio: Shapes the sound from the time of day, weather, location, heart rate and walking cadence, and follows your circadian rhythm across the day.
- Generated on the device: Creates audio in real time instead of streaming fixed tracks. The App Store listing states that all modes are available offline.
- Wearable and home devices: Runs on Apple Watch without your phone, and on Amazon Alexa devices, Fire TV and Apple TV as well as Mac, Windows and the web player.
- Artist soundscapes: Includes collaborations with musicians, such as the Wind Down soundscape made with James Blake, alongside the four core modes.
Pros
Endel’s main advantages are audio that never loops, apps on almost every device, offline playback, a simple pick-a-mode design, and published research and platform awards behind the product.
- Never loops: Audio is generated in real time, so a session can run for hours without the repetition you get from a playlist or a white-noise file.
- Works everywhere: Covers iPhone, Android, Apple Watch, Mac, Windows, web, Alexa, Fire TV and Apple TV, so the same sound follows you from desk to bedroom.
- Works offline: All modes are available offline according to the App Store listing, which suits flights, commutes and places with poor signal.
- Simple: You pick one of four modes and press play. There are no playlists to build and few settings to learn.
- Research-backed: Endel links its studies from the site, including a paper posted on bioRxiv, so you can read the method instead of relying on the headline figures.
- Recognised by platforms: Awards listed on the site include Apple Watch App of the Year 2020, Google Play Best of 2021 and a Microsoft Store award in 2024.
Cons
Endel’s main drawbacks are that it publishes no price list, limits the free edition, collects health and location data for personalisation and makes focus and stress claims that rest on its own research.
- Unclear pricing: The website publishes no price list. The App Store sells 1-month, 12-month and lifetime options, and a reviewer reports several different price points by country and promotion.
- Subscription needed: Most modes sit behind a paid plan, and the App Store listing says background mode is limited in the free version.
- Not music: The output is ambient sound without songs or lyrics, which will not suit people who prefer familiar music while they work.
- Bold claims: The sevenfold focus and 3.6 times stress figures come from research Endel itself presents, and results vary by person. It is not a treatment for sleep or stress problems.
- Data collection: The App Store privacy label lists health and fitness, location, contact, identifier and usage data as linked to you, so review each permission before allowing it.
Who is Using Endel?

What Makes Endel Unique?
Endel stands out because its sound is generated for you in the moment. Playlists and white-noise apps play the same files to everyone, while Endel changes with your body and surroundings and has won awards from Apple and Google. That makes it feel less like a playlist and more like a tool.
