Endel is an Android app that uses AI-powered soundscapes to help you focus, relax, and sleep. Developed by Endel Sound GmbH, the app uses inputs like location, environment, and heart rate to create personalized soundscapes. The app is free to download and use, but it offers a subscription service that unlocks additional features.

With Endel, you can choose from six different modes: Relax, Focus, Sleep, Recovery, Study, and Move. Each mode has its own set of sounds that are designed to help you achieve your goals. For example, the Relax mode is designed to calm your mind and create feelings of comfort and safety, while the Focus mode is designed to boost your productivity by helping you concentrate for longer.

Endel also offers collaborations with innovative artists and thinkers to create original experiences. Grimes, Miguel, Alan Watts, and Richie Hawtin have all contributed to the growing catalog of soundscapes.

The app integrates with the Health app and Wear OS app, allowing you to see the current and upcoming biological rhythms phases right on your watch face without opening the app.

Overall, Endel is an excellent app for anyone looking to improve their focus, relaxation, or sleep. While the subscription service may be a turnoff for some users, the app offers enough features to make it worth the cost.
