Read full description

There are twelve energy pathways, or meridians, in the human body that connect to specific organs in the body. Chinese medicine believes that each organ has a two hour time period when the Qi is at its peak in that meridian. The Qi flows cyclically in a clockwise rotation like a wave through the meridians. We always pay attention to symptoms that occur repeatedly at specific times because this may be an indication of the organ that is out of balance. For example, waking every night between 1 and 3 a.m. almost always is indicative of a Liver imbalance. The Organ Clock App will show you which organs correspond to which two hour period. The Organ Clock iPhone App lists the periods in which the organs are at their peak Qi. It will display the details for the organ currently at its maximum, including whether it is a Zang or a Fu organ, Yin or Yang, which element the organ belongs to and a short description of the role of the organ according to the traditional chinese medicine and tips on how to behave during that period. You can also browse all organs independent of whether they are at currently their maximum Qi or not. Disclaimer: If you think that you are suffering from an illness, please consult an qualified medical practitioner. Neither the organ clock nor the information about the specific organs can substitute for a qualified anamnesis and diagnosis. The developer of this Application is neither physician nor healer but has compiled freely available information about the organ clock and has published them in this Application.

About

Koan Meditation Timer

Features
Read full description

The Koan Simple Meditation Timer is built so you can sit down and meditate without distraction. It features three real sounds of bells and bowls and a flexible scheduler. You can create a simple session with a bell to start and a bell to finish after 10 minutes. You can just as easily make a complicated bell setup like 30 minutes of sitting meditation followed by 10 minutes of walking mediation. The simplicity is purposeful here. There is no account to create, no data saved, no push notifications of premium subscriptions to shill. We both know you don't need that. Just meditate more and the world will be a better place for it.
