This Feng Shui App Scans Your Home and Pins the Flying Stars to the Floor

The instructions on the scan screen are short: walk along the walls, catch every doorway, the bathroom and the kitchen, then move slowly past each piece of furniture until it turns green. The app is Karma Space, known in Chinese as 玄居, and it reached Hong Kong's App Store on Sept. 28, 2026. On an iPhone Pro with a LiDAR sensor, it turns a flat into a 3D model with walls, doors, windows and furniture, walks you through measuring which way the front door faces with a built-in compass, and then lays a Flying Star chart, the nine-square grid of classical Chinese feng shui, directly onto that plan. Phones without LiDAR can upload a floor plan or draw one by hand.

The demo flat in the store screenshots comes out divided into nine squares. The Nine Purple star sits in the north, marked as the wealth position, with tips attached: a screen to the north, a plant to the north, the air conditioner in the northeast. The dining chairs and the air conditioner each carry a red warning, and tabs above the model read "indoor sha (3)," "feng shui report" and "improvement plan." A consultation used to start with a master visiting in person to take compass bearings, measure and sketch the layout. Karma Space hands that step to the phone; the reading that follows is still Flying Star feng shui.

Phone apps have handled floor plans for a while, mostly in two ways. Some overlay a chart on a plan you already have: Hong Kong's Feng Shui Compass AI Master takes the door's bearing in AR, then lays the nine squares over a floor plan from your photo library and lets you ask an AI about the result. Others want only a photo. Feng Shui Hero takes a picture of a room and returns a score in seconds. Karma Space isn't the first to bring LiDAR into it either. India's SpaceFlow, on the App Store since 2025, scans rooms into a floor plan and grades them out of 100 against a 16-direction Vastu grid. What Karma Space adds is a chart aligned to true north and fixed to a model with real dimensions, staying on the floor as you rotate the view.

A "research progress" page on the company's site spells out how much it wants the phone to do. Scanning runs on Apple's RoomPlan and was finished in August and September: walls, doors, windows and furniture, auto-aligned to true north. A vision model then identifies objects frame by frame, from monitors and arcade machines to fish tanks and framed pictures, down to plant species, because the rules later treat some species as lucky and others not. The scan's point cloud is used to measure daylight, openness, how energy gathers and how people move, drawn as heat maps, before rules for doors facing doors, straight-through drafts and beds facing doors flag problems. Offices get their own rules, including a boss's chair backed by a solid wall. Multi-room scanning is in progress. Further out, the plan is to pull nearby roads, water and hills from the address, the outer landforms feng shui also reads.

The way it explains feng shui has an engineering flavor too. The site translates a door lined up with a back door or window as an airflow short circuit, an open view out front as daylight and outlook, and a gloomy, "yin-heavy" room as low light, high humidity and poor ventilation, problems that, the homepage says, take three kinds of sensors to measure today. An Aug. 25 article on the site says the AI's readings quote classical texts by passage, and the homepage counts 3,154 checked entries. Those are the company's claims; the checking itself isn't visible from outside.

It is also strict about who is answering. Anyone called xiansheng on the site is an AI, each named after a historical figure: Xu Ziping for Four Pillars readings, Guiguzi for relationships, Fan Li for career and money, Bao Gu for health routines, Yang Yunsong for home feng shui, Wang Yangming for modern life, with an AI called Jingli giving the final verdict. The directory notes they are AI advisers set up on each figure's methods, not the people themselves. Human masters are called shifu, and the FAQ says the two are never mixed and the AI won't pose as a master. That human side has barely started. On Oct. 13, the directory listed a single master, 22 years in practice, based in Sham Shui Po, tagged as new with no reviews; the FAQ says booking is opening in stages, with clients scanning their own homes and masters reviewing the model remotely.

The FAQ's most pointed answer is about whether readings are made to sound dire so you'll pay. Karma Space says every AI adviser's instructions ban frightening language and ban ending with a nudge to sign in or buy; a low-scoring day reads as "keep steady," not "very unlucky." Its human masters, it adds, won't sell ritual objects or run the "fix it or something bad will happen" routine. Public material from other apps shows the kind of thing it is promising not to do. In SpaceFlow's store screenshot, the demo home scores zero because the oven is in the northeast, which the text says leads to ailments related to the brain, ending with an instruction that the stove must be moved to the southeast. In Taiwan, SeerQ, which also pairs AI readings with human advisers and ranked No. 49 on the free Lifestyle chart on Oct. 13, drew six one-star reviews between Sept. 16 and Oct. 10 saying advisers pushed paid rituals or remedies during consultations. The one five-star review in that stretch to mention rituals warned, with a laughing emoji, that the app will have you buy one, and an expensive one.

A rule in an FAQ will only be tested once human masters take bookings and reviews pile up. For now Karma Space is tiny: 12 ratings in Hong Kong, and a homepage counter showing 150 accounts, 100 readings and 18 real homes scanned. The new part is the first half of the process, where the phone does the measuring and the nine squares sit inside a room with real dimensions. Whether the square marked "wealth" in the north really brings money is something no sensor can measure. That remains Flying Star doctrine.
