This application calculates the optimal effectiveness of acupoints: The concept of energy phases is a system which describes the changes in the constellation of energies at different periods of time. Since the flow of qi and xue through the channels is not constant but is rather of a rhythmic character, certain acupuncture points are more accessible and responsive at certain times and the ability to influence the circulation of energy via these particular acupuncture points is greater at these times. This application allows you to: - Calculate the Heavenly Stem and the Earthly Branch of the respective year, month, day and hour (Bazi, the Four Pillars of Chinese astrology) - Determine the principal acupoint according to the current date/time or any user-defined date/time and location - Determine the principal acupoint according to the Eight Methods of the Intelligent Turtle (Linggui bafa) - Determine the principal acupoint according to the so called Selection on Day Time according to the Heavenly Stems (Najia ba) - Calculate the optimal acupoints with the corrected time (True Local Time), which considers Daylight Savings Time, Longitude and Equation of Time) - Set your current location with the help of the iPhone built in localisation function or set location manually ## Key features - Calculate Heavenly Stem and Earthly Branch (Bazi) - Determine principal acupoint by date/time/location - Apply Eight Methods of the Intelligent Turtle - Utilize Selection on Day Time according to Heavenly Stems - Calculate optimal acupoints with corrected time (True Local Time) - Set location via iPhone localization or manual input ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/chrono-acupuncture/id299971564/reviews.md ### 2/5 — impossible de mettre à jour *2013-10-04* Me demande mon idnetifiant alors que je suis connecté... ### 4/5 — BUGS *2012-06-17* They are some bugs in the determination of the points to open. For example in Na Jia Fa on the 8 of March 2007 at 8 AM no points is selected. The right points is Kun Lun BL 60. ### 4/5 — Great *2010-05-20* This is a great app, pity you don't advertise on the app store that it is in English, when u look at the app page you can only see German. I took a punt in DL the app and found it's in english automatically. Would have got it sooner If i'd known. ### 5/5 — Saves so much time, I'm now on time *2009-05-14* Been waiting for someone to turn this amazing system into an application. Will I miss using my charting system? I dont think so....thank you ### 1/5 — iTouch? *2009-04-26* Leider konnte ich das Programm nicht beurteilen- mein iTouch ist trotz aktuellem Software-Update nicht kompatibel- bitte teilen Sie dies doch auf Ihrer Website mit! Außerdem konnte ich keine aktuelle Support-Adresse für dieses Problem finden...schade.... ### 3/5 — Pas mal *2009-01-23* Il falait oser. L'allemand est une langue très internationale... Heureusement appli. en anglais. 3 étoiles parcequ'il falait oser malgrès que les Bazi n'interessent presque personne. Autrement appli. un peu légère. ## Frequently asked questions about Chrono Acupuncture ### What is Chrono Acupuncture used for?
