Reviews from users
*The following contents are translations of reviews posted by Japanese users.
=====================================
■ This is the one! Version 3.5 Sept. 15, 2012
My level of concentration has increased! I have better memory too! Now I can sleep well at night!
■ Great!!
In studying or at work, I always use this app. I am hooked on it!
■ I can't live without this app!
No need to count sheep with this app! I'm out like a light.
■ My insomnia is gone!!!
I guess everyone has different results but this app has sure worked to cure my insomnia!
■ Someone with insomnia
I had a slight case of insomnia but now all that is gone after listening to this app.
■Explanation of this App
1. When a person hears two different frequencies in their ears, the difference of those frequencies will appear in the brain as one frequency. In this app that principle is used and your brain will be in a state as when you are sleeping.
2. The sound of "Flicker Noise" is known to help balance the autonomic nervous system as it enters the hypothalamus of the brain, which helps relieve pressure on the sympathetic nervous system.
Through a combination of the two above methods you will be lead directly and indirectly into a deep sleep.
※ The sound of "Flicker Noise" is the sound parameters of the background environmental sound.
How to Use
1. Start the app.
2. Choose your favorite background music.
Also, for more effective sounds through the change in settings.
Results (sleep / relaxation/ concentration, memory)
- The effects of concentrating
The mode is for increasing brain activity and raising your level of concentration before doing sports.
- The effects of memory
This mode will take you a deeper level than the relaxation mode. This mode is recommended for studying or raising your level of memory.
※ The sound which can help each person is slightly different so we suggest that you try different settings to find the sound that best works for you.
※There is no guarantee that the effect will work on everyone.
○This application uses a binaural beat technology, which has been scientifically proven effective.
However this method uses only 3db, so based on how sensitive the user is, there may be a gap in benefits received.
Even if you did not get results your first time, keep using it every day. You should slowly see better results.
○How to use this application effectively
・Close your eyes, relax and assume a position laying down.
・This application needs to use many low and high frequencies so use high quality headphones not cheap 100 yen ones.
・If your ears start to hurt, please turn down the volume until until the music is barely audible.
○ Our company has an app "3D Eyesight Recovery" to help restore eyesight using stereogram.
Stereogram uses the eyesocket muscles resulting in effectively stretching your eyes and it is said that when used before sleeping this app helps you to sleep more soundly. Why not try this wonderful app?
※ You need a special way to see Stereogram, so a little practice is required. The instructions for this are in the app.
※Binaural Beat is a technology which controls the brain waves.
For anyone with one of the following problems below, please consult your Physician.
・ For Those with Epilepsy
・ For Those with Heart Problems (especially those with pacemakers)
Do not us this app when driving or doing other dangerous work.}
