Store description excerpt
LUBAN RULER — SCROLL TO ANY SIZE, READ GOOD & BAD ZONES INSTANTLY The Luban ruler (魯班尺) is the traditional Feng Shui measuring tool used to pick auspicious dimensions — and avoid inauspicious ones — for doors, furniture, altars and home construction. This app brings all 3 standard Luban rulers to your phone: drag the ruler or type a measurement, and all three rulers read out results side by side. — 3 STANDARD RULERS, SIDE BY SIDE — • CLEAR OPENING 52.2cm (8 sections) — for main doors, windows, room doors, gates • YANG DWELLING 42.9cm (8 sections) — for kitchens, stairs, beds, cabinets, furniture • YIN DWELLING / DING LAN 38.8cm (10 sections) — for altars, ancestral tablets, tombs Every section and sub-section comes with its full name and meaning in plain English. — KEY FEATURES — • Buttery-smooth, endless scrolling; tap the number box to type a size (mm or inch) • Instant Good/Bad verdict with section names and meanings for all 3 rulers at once • NEAREST LUCKY SIZE SUGGESTION: land on a bad zone and the app tells you exactly how many mm to add or remove to reach the nearest good zone • ±1mm fine-tune buttons and quick reset to zero • Haptic ticks while scrolling, warning buzz when entering a bad zone (can be turned off) • Light & Dark themes, one-tap switch • 3 languages: English, Tiếng Việt, 中文 — switch inside the app • Detailed built-in guide explaining every section • Works 100% OFFLINE — no ads, no data collection — HOW TO USE — 1. Drag the ruler (or type a measurement) to the size you want to check 2. Read the red center line: each ruler shows its zone at that position 3. Rule of thumb: "Use the red zones, avoid the black zones" NOTE: the on-screen ruler is for looking up Feng Shui zones by measurement (use a real tape measure on physical objects). Feng Shui content is provided for cultural reference. Developed by Manh Nguyen — manh.work Feedback: manhdotme@gmail.com
