Forget about messy templates, transparencies and papers. The fourth tool of the Azure series enables you to instantly overlay the 24 Mountains anywhere on the map. Use this tool to locate the Qi mouth, mountains, water or even "Sha Qi". Both the 24 Mountains and the base map aligns automatically to the North so you dont have to worry. This app works also works on iPhone, but works superbly on big screen iPad. There is also an accompanying Lou Pan compass for general purpose use. This is definitely a great companion tool for your Feng Shui audit.
