"Mind Walk" is a sound app to make you feel deeply relaxed.
Please feel relaxed before you sleep, listening to the nature sounds as if you were walking in the forest.
The nature sound in this app consists of more than 180 natural sound fragments allocated with 1/f fluctuation algorithm, as same as our body.
The distance you walked in real life and your heart beat rate are applied to the app.
If you walked longer today, you tend to rest a lot in the app, and if your heart rate is high, you walk slower in the app.
(To reflect your heart rate, you need Apple Watch.)
Please enjoy walking in the forest of your mind.
