Below are 35 common questions in 8 groups. ## About Home Check ### What is Home Check? Home Check is the pioneering Agentic AI for Architecture & Scientific Feng Shui — a chief architect and a feng shui master in one app. It doesn't just answer, it does the work: precise orientation on satellite imagery, code-aware floor plans, feng shui checked and fixed right on the plan, and 2D, 3D drawings with a full analysis. ### Which devices does Home Check run on? iPhone and iPad (iOS 18 or later) and Android phones. Download it from the App Store or Google Play. ### Which languages does Home Check support? Three: Vietnamese, English and Simplified Chinese. Feng shui terms are translated consistently between the app and this website. ### Who is Home Check for? Homeowners about to build, renovate or buy; architects who need options fast; feng shui masters who need precise polarity and clear reports; investors, contractors, and architecture students and teachers. ### Does Home Check replace an architect or a feng shui master? No — it helps them work faster and more precisely. Results are advisory; for projects that need formal appraisal, combine them with a site survey and a licensed architect. ## Design ### What does designing a house from one sentence mean? You type or say one sentence, such as “5×20 house, 3 bedrooms, an altar room”, and get three floor-plan options, each scored from 0 to 100. The assistant asks when information is missing and advises like an architect before drawing. ### Can it design for irregular, many-sided plots? Yes. Pick a polygon plot shape, then drag the edges or type the metres to match the real outline; Home Check generates a plan that fits that frame. ### Do the options follow building codes? Yes, Vietnamese building codes; the assistant can explain the rules and name the document. Codes are chosen by project location, extending to Hanoi, Singapore, Malaysia, Taiwan and Hong Kong. ### Can it design multi-storey homes? Yes. View each floor, add floors, and all floors share one facing when you set polarity. ### Can I edit an option after it is generated? Yes. Swap rooms or change their use, add doors and furniture, resize rooms directly in the editor, or ask the assistant to do it in one sentence. ## Digitizing ### I already have a paper plan. What now? Photograph it, one photo per floor; Home Check rebuilds it as a digital plan so you can check dimensions, set polarity and check the feng shui. ### Which devices can scan with LiDAR? iPhones and iPads with a LiDAR sensor. Devices without one can still digitize from a plan photo or a Bluetooth laser meter. ### How does the Bluetooth laser meter work? Connect the meter to Home Check and measure each wall; every reading goes straight into the plan — draw as you measure. ### Can I see the home in 3D? Yes. View it in 3D, take a walkthrough room by room, and create renders from a photo of a room in the style you choose. ## Compass & water reading ### How accurate is the Home Check compass? Readings are shown in fine detail (e.g. 135.4°), with magnetic declination corrected for your location. Real-world accuracy also depends on how you measure: stay clear of metal, hold the phone flat and repeat at a few spots. ### Which mountain is a house facing 135°? The Xun 巽 mountain, from 127.5° to just under 142.5°, in the Xun trigram to the southeast, element Wood. A Xun-facing house sits in Qian (315°). ### What is the AR Compass? A compass overlaid on the camera view, so you can look straight ahead and still read the degree and mountain. ### How does Home Check find the Water Mouth? At three levels — Grand, Middle and Small scale — marked right on the map of the site, each point with a confidence level. You can also pin the Dragon Entry, Sha and Water Mouth by hand. ### Does it show wind and sun? Yes. The Measure screen shows the real wind reaching your door — current and annual — the sun's path, and automatic contour lines around the site. ## Feng shui & reading ### What is a feng shui check on the plan? A check of the whole home on a plan with polarity set: every position is coloured Good, Needs adjusting or Serious, with a score from 0 to 100 and an explanation of why. ### How does Home Check fix feng shui? Two ways: keep the layout — only move or turn items — or re-arrange; every change can be undone. When a deeper fix is needed, the thorough fix offers 3–5 scored options to choose from. ### Does Home Check consider the people who live there? Yes. Enter each member's birth year; Home Check compares each person's birth-year mountain with the door and other items and says so plainly — for example, “Main door on the Zi birth-year mountain — male head of household”. ### What is in the 9-part reading? A feng shui reading of the home laid out like a consultant's report: each room, each person and the remedies. The assistant can read it aloud and explain it, and you can export it as a PDF. ### Can I export the reading under my own brand? Yes, with the PRO tier: your logo, name, representative and phone number appear on the export. Exports always keep the line “Analysed with Home Check”. ### What is Home Check's feng shui based on? On real measurements: the exact facing degree, the 24-mountain compass, the actual position of every room and object on a plan with polarity set, and a rule set reviewed by experts. ## Tokens & tiers ### How does Home Check charge? Pay for what you use: you buy tokens in the app through the App Store or Google Play, and tokens are charged only after a task has produced its result. ### What if a result fails? When a task produces no result because of an error on the AI side, the tokens are refunded. ### What is the PRO tier? The highest card tier, unlocking features such as your own brand on exports. Once you reach PRO, you keep PRO. ### Can I transfer tokens to someone else? Yes. The app lets you transfer and lend tokens between accounts. ## Privacy & data ### Does Home Check sell my data? No. We do not sell your data; what is collected and how it is protected is set out in the Privacy Policy. ### Is my voice recorded during Live conversations? No audio is stored. Only the text of the conversation is saved so you can reopen it. ### How do I delete my account? Inside the app, in the account section; the “Delete account” tutorial walks you through each step. ### Why does the app need my location? To correct the compass for magnetic declination and to read the wind, sun, terrain and Water Mouth around your exact site. ## Outside Vietnam ### Can I use Home Check outside Vietnam? Yes. The compass, wind, sun, water method and feng shui check all work from your actual location, and the app is available in Vietnamese, English and Chinese. ### Are building codes from other countries available? Yes. Building codes are chosen by project location: Vietnam, Ho Chi Minh City and international — extending to Hanoi, Singapore, Malaysia, Taiwan and Hong Kong. --- Original page: https://myhomecheck.ai/faq Other languages: [Tiếng Việt](https://myhomecheck.ai/vi/hoi-dap/index.md) · [中文](https://myhomecheck.ai/zh/faq/index.md) Updated: 2026-10-21
