The Chinese organ clock for Android
The organ in charge now, where you are
In traditional Chinese medicine, twelve organs take turns around the clock, two hours each, and the Heart has the hours around noon.
Body Clock works out solar noon for your exact location and sets the twelve periods around it. So the clock follows the sun where you are, not a fixed table of clock hours.
Free to download. The organ running now is always free.

The organ map
The organ clock across the whole world
Which organ is in charge depends on where you are, because the sun reaches its highest point at a different time in every place.
The map shows the organ clock across the whole world as coloured bands, with a line where it is solar noon right now. It can also show all 24 hours in motion.
- Tap any point to see its organ, and save it as a place.
- Move the map to any date and time.
The app itself
Every organ in the colour of its element
The colours of the five elements run through the whole app, so the clock reads at a glance.
Scroll sideways to see them all. Open any screen to see it larger.

Questions and answers
What people ask
Why solar noon, and not noon on the clock?
Solar noon is the moment the sun stands highest where you are. On your watch it comes earlier or later depending on how far east or west you are in your time zone, and summer time moves it an hour later. The tradition follows the sun, and so does the app.
Why does solar noon move through the year?
The Earth's orbit is an ellipse and the Earth's axis is tilted, so solar noon drifts by about a quarter of an hour either way through the year. The app follows it day by day.
Does the clock work near the poles?
Yes. There is a solar noon every day, even when the sun stays below the horizon all day, so the clock works at every latitude.
Does the app need the internet?
The clock is calculated on your phone, so it works offline. The internet is used only to load the map, to look up place names and to handle payments through Google Play.
Can I choose the language of the app?
By default, the app uses the language of your phone if it is one of its 34 languages, and English otherwise. On Android 13 and later, you can also choose a language for this app alone, in your phone's settings for the app.
How do I cancel the subscription?
In Google Play: tap your profile picture, then Payments and subscriptions, then Subscriptions.
Cancel at least 24 hours before the current period ends to stop the next payment. You keep everything until the period ends.
