Where does the software of Feng Shui Golden Compass go?

A simple geomantic compass software is available on many specially downloaded websites, such as Dortmund and Pacific Download. If you can only use your mobile phone, you can download the Feng Shui Compass app directly from the mobile app store. Just to remind you, if you are a professional Feng Shui master, the Feng Shui compass downloaded to your mobile phone can't be used to show others Feng Shui. The degree deviation exceeds 5 degrees, and the orientation judgment is inaccurate. It's okay for entertainment, but if you change your major, you have to use a professional electronic geomantic compass. As shown below, but if you don't like geomantic omen very much and are deeply studying this aspect, it's not very valuable to spend thousands of dollars to buy a professional electronic compass. This is for professional feng shui master.
