Room Scanner vs RoomScan Pro: Which LiDAR Floor Plan App Should You Use?

If you searched for "room scanner pro" you have probably run into two similarly named apps: Room Scanner, the app this site is about, and RoomScan Pro LiDAR by Locometric. They are made by different companies, they are priced very differently, and they are built for slightly different jobs. This page lays out the differences so you can pick the right one without installing both.

A note on who is writing this: Room Scanner is our app. We have tried to keep the comparison factual and to give RoomScan Pro credit where it is due, because it is a genuinely capable tool with a long track record. Pricing and feature details below are taken from each app's App Store listing and developer website as of September 2026 — check the listings before you buy, as both apps update often.

The Short Version

If you want a fast, accurate floor plan and a 3D model from a single scan and you do not need insurance or BIM file formats, Room Scanner does the job for a fraction of the price. If your workflow runs through Xactimate, IFC or RapidSketch, or you need to scan building exteriors, RoomScan Pro is built for that and the subscription buys you a deeper professional toolset.

Price: The Biggest Difference

This is where the two apps diverge most, so it is worth being precise.

RoomScan Pro LiDAR is free to install, and the LiDAR scanning functionality is sold as a subscription: $9.99 per month, or $119.99 per year. Locometric also still sells the older, non-LiDAR RoomScan Classic (which used to carry the "RoomScan Pro" name) with a $39.99 one-off unlock or a $3.99 monthly plan. That older app measures rooms by touching your phone against each wall rather than scanning with LiDAR, so it is a different product from the LiDAR version most people are searching for.

Room Scanner is free to download. The free tier lets you scan up to three rooms, edit the plans and view them in 2D, 3D and AR, and it is ad-supported: the basic exports (PDF, PNG, USDZ and JSON) are unlocked by watching a short rewarded ad. A Pro subscription at $2.99 per week, $3.99 per month or $34.99 per year (App Store list prices, which vary by country) removes the scan limit and the ads and unlocks the CAD exports (DXF and SVG), the branded property report, CSV schedules, the EPC survey plan, the furniture catalog and the advanced editor tools.

Over a year, that is $34.99 for Room Scanner Pro against $119.99 for RoomScan Pro LiDAR. For an occasional user who scans a couple of rooms before a renovation, the difference is even larger, because Room Scanner's free tier already covers that job.

Scanning: How Each App Captures a Room

Both apps rely on the LiDAR sensor in iPhone Pro and iPad Pro models for their headline scan mode, and both hit similar accuracy in practice: the iPhone LiDAR sensor measures to roughly ±1 cm on features larger than 10 cm, as peer-reviewed research has shown. The difference is in how many ways they let you capture a space.

Room Scanner has one main workflow: open the app, walk the room with your camera, and the plan and 3D model are built on the device in real time. When you stop, you have both a dimensioned floor plan and a 3D model you can inspect. Press "Scan next room" and keep walking, and the app lands each room next to the ones already captured, assembling a whole-floor plan; projects stack those floors by storey. If your device has no LiDAR, you can type a rectangular or L-shaped room's width, length and ceiling height instead, and the app builds the same plan, 3D model and exports from those numbers.

RoomScan Pro LiDAR offers more capture modes. It has its own LiDAR scanning mode, Apple's RoomPlan as an alternative, a touch mode where you hold the phone against each wall in turn, and a closet mode for spaces too dark to scan. According to Locometric, most of its users pick the LiDAR mode, with RoomPlan used for around one room in ten. It also scans building exteriors and plots, which Room Scanner does not, and it pairs with Bosch and Leica Bluetooth laser measures when you want to punch in a precise reading.

For an interior floor plan, the two arrive at a similar result. RoomScan Pro wins if you need exteriors, plot outlines or laser-measure integration. Room Scanner is the simpler path from opening the app to holding a finished plan.

Output: 2D, 3D and What You Can Do With It

Room Scanner produces a 2D floor plan and a 3D model from the same scan, and you can view the model in augmented reality on site. The plan editor is non-destructive with undo: drag corners, type exact wall lengths and ceiling heights, add a door or window the scan missed, flip door swings, straighten rooms, and add point-to-point measurements, notes and photos that print on every export. Pro adds a furniture catalog with saved layouts you can compare side by side, split and merge rooms, drawing new rooms, wall thickness and named plan versions. There is also a survey mode for EPC and RdSAP energy assessments, where you classify each wall as heat-loss, party or unheated and watch the perimeter update live, and a branded property report that puts your logo, room schedule, photos and notes into a client-ready PDF.

RoomScan Pro LiDAR produces a 2D floor plan with automatic ceiling heights and wall areas, and can generate a 3D model and point cloud of the scan. It supports photo annotation, dictated notes, and Apple Pencil markup on the plan, and its FLYPLAN feature turns the plan into a 3D visualisation.

Both apps cover the essentials. Room Scanner leans towards presenting and planning: the furniture catalog, branded report and 3D inspection are aimed at agents, designers and homeowners. RoomScan Pro leans towards documentation: notes, photos and ceiling heights recorded on the plan for a survey or a claim.

Export Formats

This is the second place the apps genuinely differ, and it should drive your decision if you hand files to other software.

Room Scanner exports:

• PDF floor plan and a PNG image of the plan
• USDZ 3D model, including placed furniture, for Apple Quick Look, Blender, Archicad and other 3D editors
• JSON to move a scan to another device
• With Pro: a branded property report for clients, a CSV room and window schedule, a one-page EPC survey plan, and DXF and SVG drawings that open in AutoCAD, SketchUp and most CAD packages

RoomScan Pro LiDAR exports a much longer list: PNG, PDF, DXF, IFC, FML, Xactimate ESX, Sweet Home 3D, OBJ, PLY, XYZ, RapidSketch and Metropix, with USDZ and PLY used for sharing 3D models and point clouds.

If any of IFC, Xactimate ESX, RapidSketch or Metropix mean something to your workflow, RoomScan Pro is the right choice; those are specialist formats for BIM, insurance estimating and property marketing that Room Scanner does not produce. If what you need is a PDF for a client, a DXF for an architect, or a 3D model to share, Room Scanner covers it, and the PDF, PNG, USDZ and JSON exports are included on the free tier.

Device Support

Both apps need Apple hardware, and both need a LiDAR sensor for scanning: iPhone 12 Pro or any later Pro or Pro Max model, or an iPad Pro from 2020 onward. Standard iPhones do not have the sensor.

Room Scanner installs on any iPhone or iPad running iOS 17 or later (and on Apple silicon Macs as the iPad app); without LiDAR you get manual room entry instead of scanning. RoomScan Pro LiDAR requires iOS 17.6 or later and runs on Apple silicon Macs as well. Neither app is available on Android; if you need an Android floor plan app, our guide to floor plan scanner apps covers cross-platform options such as magicplan.

Track Record and Reviews

RoomScan Pro has been on the App Store for well over a decade and has built up more than 2,000 ratings on its LiDAR version, averaging 4.3 out of 5 as of September 2026. Room Scanner is newer, with a smaller number of ratings that also average 4.3 out of 5 at the time of writing. If a long history and a large review base matter to you, RoomScan Pro has the edge. If you would rather judge the app on the plan it produces, both are free to try on your own rooms in a few minutes.

Which One Should You Choose?

Choose Room Scanner if:

• You want an accurate 2D floor plan and a 3D model from one scan, with no subscription to start
• You are a homeowner, real estate agent, interior designer, tradesperson or EPC assessor producing plans for clients or your own projects
• You want to plan furniture layouts, classify walls for an EPC survey, or share a branded report
• You need CAD export and would rather pay $34.99 a year than $119.99

Choose RoomScan Pro LiDAR if:

• You need exports for Xactimate, IFC, RapidSketch, Metropix or Sweet Home 3D
• You scan building exteriors or plots as part of your work
• You use Bosch or Leica laser measures and want them feeding the plan directly
• You want several capture modes for tricky spaces, such as closets or rooms where a wall-touch approach is easier than a scan

For most people who searched for a room scanner app, the first list describes their job. Download Room Scanner free and scan a room; if you find you need a format it does not export, you have lost nothing.

FAQs

Is Room Scanner the same app as RoomScan Pro?

No. Room Scanner is developed by Grumsen Development ApS in Denmark. RoomScan Pro LiDAR (and the older RoomScan Classic) are developed by Locometric in the UK. They are separate apps with different pricing and features, despite the similar names.

Is there a free version of RoomScan Pro?

RoomScan Pro LiDAR is free to install, but the LiDAR scanning is sold as a subscription at $9.99 per month or $119.99 per year as of September 2026. Room Scanner is free to download: the free tier includes three LiDAR scans, 2D floor plans, 3D and AR views and the plan editor, with PDF, PNG, USDZ and JSON exports unlocked by a short ad; Pro removes the limits and ads and adds CAD, report, CSV and EPC exports.

Which is more accurate, Room Scanner or RoomScan Pro?

Both use the same LiDAR sensor in your iPhone or iPad and land at similar accuracy, around ±1 cm on features larger than 10 cm. Differences in results come down to how carefully the room is scanned rather than the app.

Does Room Scanner export to DXF like RoomScan Pro?

Yes. Room Scanner exports DXF and SVG on the Pro tier, which open in AutoCAD, SketchUp, Archicad and other CAD software, and every edit made in the plan editor flows into the CAD file. RoomScan Pro exports DXF as well, plus specialist formats such as IFC and Xactimate ESX that Room Scanner does not offer.

Can either app scan without LiDAR?

RoomScan Pro's touch mode and the older RoomScan Classic measure rooms by holding the phone against walls, so they work without LiDAR. Room Scanner does not scan without LiDAR, but on any iPhone or iPad you can type a rectangular or L-shaped room's dimensions and the app builds the same floor plan, 3D model and exports from them.

What is a good RoomScan Pro alternative?

If you want a lower-cost app that still produces accurate floor plans and 3D models from a LiDAR scan, Room Scanner is a direct alternative and is free to start. For a wider look at the category, see our comparison of the best floor plan scanner apps.
