What Is Apple RoomPlan? Simple Guide for AR Apps

You are scoping a room planner or a furniture app, and someone has told you Apple already solved the hard part. There is an API that scans a room and hands you a 3D model. So the question on your desk is simple: is Apple RoomPlan the shortcut that removes months of work, or is it one piece of a much larger build? This guide answers that from the point of view of a team that has shipped AR, not a brochure.

What is Apple RoomPlan?

Apple RoomPlan is an API that turns a phone walkthrough of a room into a clean 3D model. In Apple's own words it is "a new Swift API that utilizes the camera and LiDAR Scanner on iPhone and iPad to create a 3D floor plan of a room, including key characteristics such as dimensions and types of furniture" (Apple RoomPlan). It first shipped with iOS 16.

The word that matters is parametric. RoomPlan does not just give you a rough mesh of points. It gives you a structured model where a wall is labelled as a wall, a door as a door, a sofa as a sofa, each with its own dimensions and position. That structure is what makes it useful to an app, because your code can reason about "the north wall" or "the window" instead of a soup of triangles.

The output is a USD or USDZ file. Apple states RoomPlan "outputs in USD or USDZ file formats that include dimensions of each component recognized in the room, such as walls or cabinets, as well as the type of furniture detected." Because it is USDZ, the model opens in design tools and in Quick Look on iOS. If the file formats are new to you, our sibling guide on USDZ and glTF for AR explains why iOS uses one and Android uses the other.

How does RoomPlan actually work?

RoomPlan combines three inputs: the camera feed, the LiDAR depth sensor, and on device machine learning. ARKit tracks where the phone is in space as you move. LiDAR measures the distance to every surface directly, so the geometry has real scale from the first second. The machine learning model reads the shapes and labels them as walls, openings, windows, doors and furniture types. This is the part every competing article skips, so here is the mechanism in plain terms.

The scan is a live session. As you walk the phone around, Apple gives you a "dollhouse visualization that shows everything in the room that has been recognized," plus a built in coaching UI that tells the user to slow down or move closer. You can use that ready made scan experience, or build your own on top of the raw session, which matters when you want your own branding and guidance.

What you get back is a structured object that describes the room. It groups the space into surfaces and objects. Surfaces carry an architecture category: wall, opening, window or door. Objects carry a furniture category such as table, bed, sofa or chair. Every surface and object also carries its dimensions, a 3D position, a unique identifier, and a confidence level, low, medium or high, so your app can decide whether to trust a given piece or ask the user to rescan. You can read the full data model in the RoomPlan developer documentation.

LiDAR is the reason the scale is trustworthy. A camera alone has to guess depth from motion, which drifts. A depth sensor measures it. If you are weighing whether that sensor is worth designing around, our guide on whether you need LiDAR for an AR furniture app covers the trade off in detail, and how to get accurate AR measurements covers the maths of trusting a scan.

What can RoomPlan do, and what does it not do?

RoomPlan does the scan, the labelling and the export. It does not build your product, your interface, your catalogue or your Android version. The table below is the honest capability list, and the two columns after it show the split between the work Apple has done for you and the work that is still yours.

Read that "No" column carefully, because it is where the real budget goes. A room scan is a striking demo. A shippable app is the accounts, the pricing, the 3D product models, the editing tools and the fallbacks for every device that cannot scan. RoomPlan removes one hard problem and leaves the rest standing.

RoomPlan vs ARKit: which one do you need?

They are not rivals, they are layers. ARKit is the foundation that tracks the device, understands planes and handles the AR session. RoomPlan is a focused API built on top of ARKit that produces a room model. If your app only needs to scan a room and place furniture inside the scanned model, RoomPlan may be most of what you need. If you need custom occlusion, object anchoring, body tracking or your own capture flow, you drop down to ARKit, often running alongside RoomPlan.

The bigger fork is platform. RoomPlan is iOS only. There is no Android equivalent from Apple, so a cross platform app needs a second scanning approach on Android using ARCore, with different data and different quality. That decision shapes your whole architecture, which is why we treat it as a first day question, not a later one. Our comparison of ARKit and ARCore for AR apps lays out what each platform actually gives you.

The honest limits: where RoomPlan falls short

RoomPlan is good at what it does. It is worth being just as clear about what it does not do, so you plan for it instead of discovering it in testing.

• Device reach. LiDAR lives only on Pro iPhones and iPad Pro models. A large part of your potential users hold a standard iPhone or an Android phone and cannot run a scan at all. For a consumer app, that is not a small gap.
• iOS only. There is no Android RoomPlan. Cross platform means building and maintaining two different scanning paths, which is real engineering, not a config flag.
• Room sized, not building sized. RoomPlan is built for one room at a time. Long corridors, very large open spaces and whole houses in a single pass are where quality drops. You scan a home room by room and stitch the results yourself.
• Geometry, not materials. You get shapes, sizes and categories, not the real colour of the wall or the fabric of the sofa. Photo real texture is a separate job.
• Hard surfaces still fool it. Mirrors, glass, dark or reflective surfaces and poor light degrade any depth scan. A rushed walkthrough gives a rough model. The confidence levels exist precisely because not every scan is clean.
• It is not the app. This is the one teams underestimate. RoomPlan gives you an empty measured room. Everything a customer came for, the products, the drag and drop, the saved designs, the checkout, is yours to build.

Where RoomPlan fits a furniture or room planner app

RoomPlan earns its place when your app genuinely needs the real room, not just an object floating on the floor. Apple points at real estate, e-commerce and hospitality, and says these scans "can also be the first step in architecture and interior design workflows." In practice, the strong fits are:

• Interior and furniture planners where the user wants to see a whole room laid out to scale, not one chair at a time.
• Real estate and rentals that need a quick, dimensioned floor plan from a phone.
• Fit checks for large items like wardrobes, kitchens and sofas, where "will it fit" is the whole question.
• Design and renovation tools that use the scan as a starting canvas for professionals.

If instead your app only needs to drop a single product into the camera view, a full room scan is more than you need, and plain ARKit or even WebAR may serve better. Our post on WebAR versus a native AR app covers that lighter path.

Is RoomPlan enough for your app?

RoomPlan is enough only if the scanned room is your finished product. For almost every commercial app it is not, because the value is in what the user does after the scan. Use this simple rule: RoomPlan handles capture, you handle everything the customer touches. So budget for the capture as nearly free, and budget honestly for the rest.

The parts you build around the scan usually include a 3D catalogue of your own products, and that catalogue is often the largest line item in an AR furniture build. Every product needs a clean, optimised 3D model, sized correctly, exported for iOS and Android. Our guide on how to make 3D models for an AR furniture app explains why this scales into real money, and if you are at the idea stage, how to turn an idea into an app covers the steps before you write a line of code.

What does it cost to build around RoomPlan?

The scan is free. The app is not, and the cost depends on five drivers: the size of your 3D product catalogue, whether you need Android as well as iOS, how much editing and design the planner allows, the account and commerce features behind it, and how you serve users without a LiDAR device. A single room demo is cheap. A catalogue at scale and a two platform build are not.

To put a floor on it, appico's published starting prices are a mobile app from $12,000 and an MVP from $10,000, with larger, multi platform builds running up to around $150,000 depending on scope, and maintenance handled as a separate monthly plan. A retail AR planner with a real catalogue sits well above the MVP floor once the 3D pipeline is included. You can size your own case with our app cost calculator, and a fixed scope app development team can turn a RoomPlan proof of concept into a shippable product. For a worked example in the same retail AR space, see the cost and time to build a virtual try on fashion app.

Our take

RoomPlan is one of the best gifts Apple has given AR product teams, and it is also the most misread. It removes a genuinely hard problem, room capture with real scale, and it does it with a clean, structured output. That is worth a lot. The mistake is treating the scan as the product. It is the first ten percent of a furniture or planner app, and a well built ten percent, but the other ninety percent, the catalogue, the interface, the cross platform reach and the commerce, is the work that decides whether people use it.

So scope it with clear eyes. If your users are on Pro iPhones and the room itself is the point, RoomPlan is a strong foundation to build an AR app on. Bring us a proof of concept and a device list, and the honest first conversation is which parts RoomPlan already covers and which parts you are really paying to build.
