Ryohin Keikaku, the Japanese company best known for its consumer goods-focused retail chain Muji, recently introduced a sleep-inducing app called ‘Muji to Sleep‘. It is available in several different languages for Android and iOS.
The company introduced a series of neck cushion products last year, which have been getting a good reputation, especially from frequent travelers who take long-haul flights. The mobile app was recently introduced as a sister product of the cushion products.
Muji to Sleep offers six different relaxing natural sounds recorded around Japan using the binaural recording method, where the audio frequency gap between left-ear and right-ear channels syncs with the brainwave cycle and induces a sound sleep.
