Endel

Endel offers cross-platform synchronization, so the soundscape will continue seamlessly when you switch between devices. Your current Focus, Relax, or Sleep session will adapt to the new device without interruption, ensuring a consistent audio experience wherever you go. Make sure you are logged into the same Endel account on both devices.

Endel operates on a subscription basis, and refund policies depend on the platform through which you subscribed (e.g., Apple App Store, Google Play Store). Typically, cancelling a subscription before the renewal date will prevent future charges, but you may not receive a prorated refund for the remaining time. Review the specific terms and conditions of your subscription platform for details.

Endel requires an active internet connection to initially generate and personalize the soundscapes. Once a soundscape is actively playing, it can continue to function offline for a limited time. However, to ensure the soundscape is adapting to your real-time environment and biometrics, periodic internet connection is needed.

Endel states that its algorithms are validated by peer-reviewed studies. While specific study citations may be available on their website (endel.io) or through their support channels, it's important to note that research in this area is ongoing. Look for studies examining the effects of adaptive soundscapes on cognitive performance, stress reduction, or sleep quality to better understand the scientific basis.
