Interior design
The interior design and floor planning market rests on one simple thing: people want to see their actual space in a new look or on a plan before spending money on a renovation and furniture. Demand splits into three clear groups, and the leaders break in each one differently. The first and hottest group right now is AI photo restyling: a person shoots their room and asks to see it in another style. , Arch, , , , , , , Deko, Interio, Homely AI and dozens of clones all crowd in here, and almost all of them fail the same way: the AI does not look at the photo you sent, it draws a stranger's room with different windows and walls. From Deko: the app just returned the exact same picture. From Cozy AI: it put a sofa in front of the door, erased the staircase, blew up the patio tenfold. From Interior design by : three or four ovens in the kitchen, two TVs in the living room. People write again and again that they only asked to repaint a wall or swap a sofa and instead got demolished walls and a new layout, and that ChatGPT does a better job than the specialized app. The second group is drawing a plan and laying out furniture in 3D: , , , , , Roomle, , 4Plan, , , Rooms. The ask here is different, to draft a space at exact dimensions, place real furniture and not lose your work, and this breaks on precision and on keeping the file safe: a wall will not snap to 5 feet 7 inches because the editor sticks to whole feet, you cannot add a second floor, and after an update the project you sat over for hours simply vanishes. From : move one wall and the neighboring dimensions change, so they gave up and drew it on paper. The third group is camera measuring: Polycam, , RoomScan, AR Plan, CamPlan, , MeasureSquare. Here they pay for one thing, point the phone and get a plan and dimensions you can trust, but accuracy drifts on oddly shaped rooms, it lies past 5-6 meters, several rooms will not stitch into one scan, and after done the scan is lost. For a builder the picture is this: the niche is overheated with identical AI wrappers that cannot hold a real photo, and whoever honestly closes even one job without lying has almost no competition underneath.

The players fall into several types. Indies with a one-time purchase or a modest subscription (, , , , , , Rooms) win by letting you draft a plan and place furniture without a cloud or an account, people love them for years, but their own reliability finishes them off: crashes, losing a project after an update, and walls snapping to whole feet. Mainstream planners on subscription (, , Roomle, , , Polycam) are strong on furniture catalogs and 3D, but they hide the basics behind payment, lose your work when switching between 2D and 3D, and force you to enter a card before showing the product. A separate and loudest layer is AI restyling (, Arch, , , , , Deko, , Interio, Homely AI, DecoLab), where almost all are built on one model: pretty ads, and at the output a stranger's room that does not obey the prompt and changes the structure, while several apps are clearly review-farmed (AI Decor, , Abode literally beg for five stars before you enter). stands apart, it is not an editor but live designers and furniture purchasing, and what breaks there is the connection to the designer and customer support, not the AI itself. Pro tools (, , , MeasureSquare, ) are strong with specialists but are fully locked behind subscription and scare people off with a steep learning curve. The common weakness of every honest player is one: not one of them has yet learned to reliably preserve the real geometry of a space, whether it is a photo you sent or a plan you drew.
Audience
"Interior design" is not one customer. Inside are different people with different jobs, and they pay very differently. First you choose who you build for.

Live Home 3D Pro: House Design4.5 in store · genuine · 951 ratings74our scoreThis is a serious design tool that people run their whole house through for years for building and remodeling, valuing the many ready-made objects, clear 3D, sync across Mac, iPad and iPhone, and a one-off purchase instead of a subscription. It breaks on scale and stability: furniture sizes drift (3-meter beds) and cannot be resized, the 3D view distorts room proportions, objects float into the air, wall height cannot be changed separately, and lately the app started crashing after a minute and losing edits. Some complain that premium differs little from the free version and that support is slow.

MeasureSquare Mobile4.6 in store · genuine · 1,389 ratings68our scoreFlooring pros value this as the best estimating tool for carpet and floors: measure on site, and the plan is instantly in the office for a quote and material order, and it counts even floating stairs accurately. It breaks on reliability and small things: it freezes mid-measure and erases all the work, there is no inches-only mode, exporting diagrams is heavy, it is pricey for occasional use and has a long learning curve. Some report they could not cancel billing for months.
Best estimating tool for carpet and floors, field measuring with the plan straight to the office, accurate stair calculation including floating stairs, saves time on quotes, many jobs on iPad
Freezes mid-measure and erases all work, no inches-only measurement mode, clunky diagram export, long learning curve, pricey for occasional use, login trouble after registration

Interior Design PRO4.0 in store · genuine · 541 ratings66our scoreA powerful, flexible planner that fans use for years to furnish a whole house, valuing control over every detail and a large free set. It breaks in three spots: almost no tutorial or help, moving one item scatters the whole room, and some once-free features and furniture moved behind payment.

Houzz - Home Design & Remodel4.8 in store · genuine · 322,283 ratings62our scorePeople keep Houzz for years for inspiration and remodel ideas, and the photo galleries get praise. But newer versions removed in-app shopping, many images load as placeholders, and the feed keeps repeating the same homes. A real pain point: contractors aren't vetted, one user lost money to a fraudster, and buyers get pulled into a yearly contract after a monthly trial.
Beautiful remodel ideas, huge library of interior photos, easy to collect references over years
In-app shopping removed, many photos load as placeholders, feed repeats the same homes, contractors aren't vetted, relentless emails and pushy paid contract
People mid-remodel or building a house who gather interior ideas and are fine browsing rather than buying in-app
Live Home 3D - House Design4.6 in store · genuine · 18,581 ratings62our scoreA strong tool for anyone willing to learn it: 3D view, walk-through of your house, AR mode and tons of items genuinely impress. But the interface confuses beginners, walls and floors sometimes vanish, and the big pain is that without paying you can only open your most recent project, which leaves many feeling cheated.
3D view and house walk-through, AR mode, lots of items and options, no ads, you can build a house in a couple of hours
Only your latest project opens without paying, hard interface for beginners, walls and floors disappear, lags and won't load, flickering room lights
Patient hobbyists and teens who enjoy building a house in detailed 3D, not just quick previews
Keyplan 3D - Home design4.6 in store · genuine · 5,176 ratings62our scoreOne of the few planners people come back to for years and across several moves: they praise the simple interface and not having to hunt for a specific furniture brand. It stumbles on precision and on lost purchases: you can't type a wall length as a number, snapping overshoots the size you want, there's no second floor, and purchased packs suddenly vanish with no way to restore them.
Simple clear interface, quick to learn, no need to hunt for specific furniture brands, people return to it for years
Can't type a wall length as a number, snapping overshoots the target size, no second floor, purchased packs disappear and won't restore, occasionally crashes and hangs on load

Polycam 3D Scans & Floor Plans4.7 in store · genuine · 42,607 ratings60our scoreFor pros this is a strong tool: fast and accurate LiDAR, realtors scan homes, film crews and archaeologists capture spaces, and the open output format gets praise. But the company keeps reshuffling tiers and pushing needed features into pricey plans, the price multiplied, and the promise to grandfather long-time users was broken. Add crashes during work scans.
Fast and accurate LiDAR scanning, works for realtors, film and archaeology, open output format, more accurate than competitors
Features keep moving into pricey tiers, price multiplied, long-time users not grandfathered, frames capped at six megapixels, crashes during work scanning
Professionals like realtors, kitchen designers and set builders who need accurate measurements and 3D scans and will pay
RoomScan Classic4.3 in store · genuine · 4,955 ratings60our scoreQuickly sizing up a room by holding the phone to the walls genuinely works for people, and the developer replies fast and helps personally. But on non-rectangular rooms, bay windows, corner fireplaces and archways it all falls apart: walls are hard to place, corners hard to square, and rooms hard to merge into one plan. Plus complaints about a sharp price hike and paid Pro sometimes not being recognized.
Fast room measurement with the phone, simple scanning, responsive developer who fixes issues in hours, kept for years for convenience
Breaks on non-rectangular rooms, bay windows and archways, hard to square corners and merge rooms into a plan, crashes when scanning several rooms, paid Pro not always recognized, sharp price increase
