AR Meter: Tape Measure Camera

Review by eFreeware

Anyone who has stood in a furniture showroom wondering whether a sofa will fit through the front door will recognize the appeal of AR Meter. It is a free Android app from Galaxy studio apps that uses the phone's camera, together with Google's ARCore platform, to measure surfaces and distances without pulling out a tape. The people most likely to want it are DIYers, interior designers and shoppers who would rather check a dimension on the spot than guess.

What it offers is a set of measuring jobs in one place: height checks, distance readings, and scans of a room's surfaces, all done through the camera lens with the numbers shown live on screen. Measurements can be annotated, saved as screenshots and shared, which turns the phone into something closer to a notebook of dimensions than a single-purpose gadget.

The app has been installed more than 5 million times and holds a 3.5 average from 16,691 ratings, figures that suggest plenty of people have tried it and a fair number have come away with reservations. That is worth keeping in mind as you read on, because the developer is upfront about the conditions under which the tool works best.

Measuring a room before you commit to a layout

The core job here is taking the camera around a space and letting ARCore detect the surfaces in front of you. The developer describes scanning whole rooms with the room scanner, which is the part that would matter most to anyone planning a makeover or working out how much paint, flooring or furniture will fit. You point the phone, pick a plane, and the app reports dimensions for what it sees.

Horizontal surfaces like floors and tabletops are the obvious starting point, but the app also handles inclined and vertical planes. That matters in real rooms, where walls are rarely the only thing you need to measure and a sloped ceiling or a leaning surface can throw off a simple estimate. The developer says any plane can be selected once surface recognition picks it up.

The latest version adds a way to select a surface through image recognition, which requires downloading a target image first. The developer points to the app's website and screenshots for the details of how that works, so it reads as a feature for people who want more control over which surface the app locks onto rather than a change to the basic measuring flow.

Height checks and quick distance readings

A second job is the straightforward height measurement. Bookshelves, doorways and the height of a room are the examples the developer gives, and the appeal is the same in each case: a quick vertical reading without balancing a tape against the wall or asking someone to hold the other end. For anyone sizing a doorway before buying a piece of furniture, or checking clearance above a shelf, that is a genuinely useful shortcut.

Distance measurement works along the same lines. The app is meant to stand in for a tape measure while you are out shopping, which is the scenario where a phone-based tool makes the most sense, since the alternative is either carrying a tape or coming home with the wrong size. It is also described as suitable for estimating materials, where a close figure is usually good enough to build a budget from.

The app shows dimensions live through the camera lens, and measurements can be edited or repositioned without stopping what you are doing. Annotated screenshots can be saved to the gallery and shared, which is the feature I would expect to matter most to anyone working with someone else, whether that is a client, a partner or a contractor who needs to see the numbers rather than hear them.

What the app needs before it will work

AR Meter relies on Google's ARCore augmented reality system to detect surfaces and produce measurements, and your device has to be compatible with it. That is the first thing to check before installing. Keeping the ARCore library updated also matters.

There is a caveat attached to the results themselves, and it is one the developer does not hide. Measurements can come out imprecise for reasons including lighting conditions, camera quality and the type of surface being detected. The app is described as useful for getting a general idea of dimensions, with the advice that results should be verified by other methods before they are used in anything important.

That framing shapes how I would treat the app. It is a tool for estimates, quick checks and planning, not a replacement for a tape when a precise figure matters. If you go in expecting indicative numbers rather than exact ones, the experience described makes sense; if you need a measurement you can cut materials to, the guidance is to confirm it another way.

Where it fits in a toolkit

The people who get the most from this are those who measure often but casually: someone redecorating a room, a DIYer working out what will fit in a space, an interior designer doing a first pass before bringing proper tools to a job. Students, renters sizing up a new apartment and shoppers checking furniture dimensions all fall into the same group. The app is free to install.

Professionals who need dependable figures will find the developer's own advice points them toward double-checking with another method, which is a sensible way to use a camera-based tool. The app is best treated as a first measurement that saves you a trip or a phone call, with the final number confirmed by something more traditional when the stakes are high.

AR Meter has been updated as recently as November 10, 2025, with version 2.14 bringing a full-screen view, small bug fixes, a library update and improved tracking performance, so the developer is still working on the parts that affect how reliably surfaces are picked up.

A camera tape measure for planning, not precision

AR Meter is worth installing if you want a free way to get rough dimensions from your phone, and you have an ARCore-compatible device to run it on. It covers the jobs most people actually need, from a quick height check at a doorway to a scan of a room before you start moving furniture around, and it saves and shares what you measure so the numbers do not have to be remembered.

The app suits DIYers, decorators and shoppers who measure as part of everyday planning rather than as part of a trade that depends on exact figures. The developer's own note that readings are indicative, and should be verified before they are used in important projects, is the right way to approach it. Treat AR Meter as a fast first estimate and it does the job it is built for.

The app was released on September 14, 2022, and its recent updates suggest the tracking side is still being refined. For anyone who wants to leave the tape measure in the toolbox and get a usable number from the camera in front of them, this is a reasonable place to start.
