## What is AcuRhythm Acupuncture?

AcuRhythm Acupuncture Free is a free (Ad supported) version of AcuRhythm Acupuncture Pro, with some reduced functionality. It is an  acupuncture app for classical/traditional acupuncturists interested in chrono-acupuncture. The app calculates 'open' points using various theories including:
Nai Zi Fa, Zi Wu Liu Zhu (Stems & Branches, Midday/Midnight, Adopting Stems, Husband/Wife, Same Clan), Inter-Generation (24 minute open points), Wei Qi Clock, Ling Gui Ba Fa (Eight Techniques of The Mysterious Turtle) and Fei Teng Ba Fa (Eight Techniques of Soaring). Seasonal points based on the 5 shu points.
Propitious/Ominous days and Spirit human dwelling locations based on Stems and Branches.
Age-based information page, including: multiple annual spirit locations (treatment prohibitions); biorhythm data.
Moon age (days) for selected date.

28.8 minute cycle theory based on the work of Dr. Igor Simonov.
Points based on the I Ching using favorable Hexagrams and Season Hexagrams.

AcuRhythm has two time settings: Local time, or Local solar time calculated using your current longitude (the recommended method).

Point information is given by Channel, including: Source, Luo, Xi-Cleft, 5 Shu, Entry/Exit, 5 Element techniques such as the 4 Needle Technique (Korean Sa-Am), Dr Richard Tan's 5 Systems and Dr Chao Chen's Six Channel ZangFu Method. New functionality BaZi Eight Pillars calculation for 2 dates. New functionality Manaka's Daily Biorhythmic phases.
