FS Ruler brings the traditional Chinese Feng Shui ruler (门公尺) to your phone or iPad — no physical ruler required.
MEASURE YOUR WAY
• AR Mode: point your camera at two points and let augmented reality measure the real-world distance for you.
• Manual Mode: already have a measurement? Type it in directly.
READ THE RESULT
Every length maps onto the ruler's traditional 42.96cm cycle, divided into 8 categories (32 segments in total) — from "Cai De" (Fortune Arrives) and "Da Ji" (Great Fortune) to cautionary segments like "Tui Cai" (Wealth Diminishes). Each result shows its Chinese characters, pinyin, and a plain-language meaning, repeating consistently across all 10 cycles of the ruler.
BUILT FOR EVERYDAY USE
• Works on iPhone and iPad, portrait or landscape
• Available in English, Spanish, French, German, Portuguese, Russian, Japanese, Korean, Hindi, and Indonesian
• Clean, focused interface — line up your measurement and get your answer in seconds
