📝 About this app

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.

★★☆☆☆ Cited by wikipedia
Cited by wikipedia instead of reliable source. Incorrectly states the heart governs blood when the organ that governs blood is SP. Seems correct in reference to other organs. However, overall, not a reliable source for a quick reference to …
★★★★☆ Great for students and patients!
This is a pretty cool App. Everytime you open this organ clock app, it tells you in real time which organ is associated with the current time of day. If you are waking up at a certain time each night, open the app and see the organ that is …

★☆☆☆☆ Overpriced.
Not worth $2. Wouldn’t be worth it for free. A few sentences about each two hour segment that can easily be found for free online. That and a GUI that gives you a digital clock. Period…
★☆☆☆☆ Not worth the money
Overpriced for what you get!!!…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
