Orphic LuoPan

Keep a clear record of the places you measure. Orphic Luo Pan combines a 24 Mountains reference with floor-plan annotations, repeated measurements, and illustrated PDF reports. MAP YOUR HOME Import a floor-plan image. Set its reference center and magnetic orientation. Mark named places by room with a 24 Mountains overlay. A place’s bearing from the center is separate from its measured facing direction. REPEAT AND COMPARE Save 3–12 readings per session using the phone compass or entered instrument readings. Inspect original values, circular mean, maximum deviation, and sector-boundary warnings. Compare the latest two sessions at the same place. KEEP AND SHARE Organize multiple homes locally. Export a PDF with the plan, places, original readings, sources, and limitations. You choose whether and where to share it. GET STARTED Explore an explicitly labeled example home without a sensor. No account or purchase is required. Available in English, Simplified Chinese, and Thai. LOCAL RECORDS Plans and measurement content stay on your device unless you export and share them. Technical usage and diagnostics help maintain the app. LIMITATIONS Readings use magnetic north, not true north. Sensors, magnetic cases, metal, and electronics can affect results. Set the reference center and plan orientation yourself. This is a cultural reference and record-keeping tool, not an engineering survey, accuracy certification, or prediction.
