Apple Measure is a genuinely useful little app. It comes pre-installed on supported iPhones, it opens fast, and for a quick "will this shelf fit in the trunk?" check it does the job. So this page is not going to tell you Apple Measure is bad — it isn't. It is going to tell you where it stops, and what you get when you need more than a single line on the screen.
Measure Tools is what phone measuring looks like when it's built for real projects — on iOS and Android. Measure distances, heights and angles; capture whole 2D shapes with their area and perimeter in one pass; then go 3D: preview true-size boxes and furniture in your actual room, walk around a layout before you commit to it, raise a virtual wall to see a partition, and turn the room into a floor plan you can view in 2D and 3D. Every measurement can be saved as a photo with the numbers overlaid, so nothing gets lost between measuring day and buying day. It adds up to a comprehensive toolkit for renovation, furnishing and home design — free to download, so you can try it on your own rooms and see whether it earns a place in your workflow.
Credit where it is due. Apple Measure is a good fit when:
If that describes all of your measuring, keep using Apple Measure. Seriously — it is the right tool for that job.
The people who search for apps like Apple Measure usually are not unhappy with the measuring itself. They hit one of these walls:
The honest way to compare is feature by feature. One caveat before the table: Apple updates the Measure app with iOS releases, so the Apple Measure column reflects the app at the time of writing — check the version on your own iPhone for the current state. The Measure Tools column reflects the current app.
| Feature | Apple Measure* | Measure Tools |
|---|---|---|
| Horizontal / floor measuring | Yes — straight point-to-point lines | Yes — dedicated horizontal mode for floor-level distances |
| Vertical / height measuring | Point-to-point lines can run vertically; no dedicated height mode | Yes — dedicated vertical mode for wall and object heights |
| Chain measurements | Multiple separate lines in one session; no linked chain totals at the time of writing | Yes — connected point-to-point chains for baseboards, counters and wall runs |
| Angle measuring | No dedicated angle mode (the Level tab shows device tilt) | Yes — measure angles between surfaces and edges in AR |
| Area & perimeter measuring | Only when it auto-detects a small rectangular object (poster, tabletop); there is no way to trace a floor or room for its area, and no perimeter is shown | Yes — close a chain measurement around any shape, even complex ones, and the area and perimeter are calculated automatically |
| Rectangle mode | Automatic rectangle detection when a surface is recognized | Yes — deliberate rectangle measuring for door frames, windows and tabletops, included with the Measurements subscription |
| 3D box & cylinder preview | No | Yes — preview a true-size 3D box or cylinder in your space to judge whether a rectangular or round item will fit (included with the Measurements subscription) |
| Saved measurements with photos | Screenshots and copy-to-clipboard; a recent-measurements list on some devices at the time of writing | Yes — save measurements with photos, organized into folders; two folders in the free experience, unlimited folders with the Measurements subscription |
| Floor plans | No | Floor Plan mode with saved projects and 2D/3D viewing (premium 3D Planning tier) |
| Furniture planning | No | Custom real-size furniture planning — place and resize adjustable 3D furniture models in AR. Try it free — the Measurements plan includes a starter selection of furniture types; 3D Planning unlocks all adjustable furniture types with unlimited placements |
| Virtual walls | No | Virtual Wall mode — place a life-size virtual wall along a floor edge to preview a partition; included with the Measurements subscription |
| Bubble level | Yes — the Level tab | Yes — bubble level with automatic flat and edge modes |
| Onscreen ruler | No (not at the time of writing) | Yes — DPI-calibrated straight and ring rulers directly on the screen for small objects |
| Editing placed objects | Limited — lines can be removed and redone | Yes — duplicate, resize, move, rotate and delete placed objects |
| Android availability | No — iPhone and iPad only | Yes — iOS and Android |

Worth knowing before the pricing talk: everything Apple Measure does — basic AR measuring, with no limit on how much you measure — is in Measure Tools' free, ad-supported experience, alongside a free bubble level and a free DPI-calibrated onscreen ruler. The subscriptions only unlock the additional toolset. Switching costs you nothing.
How Measure Tools plans work: the app is free to download, with free tools and premium subscriptions. The Measurements subscription unlocks every measuring mode and unlimited measurement folders. The 3D Planning subscription includes everything in Measurements and adds floor plans and unrestricted custom real-size furniture planning.
You can try premium features free before subscribing, so you can judge the toolset on your own rooms first.
…your measuring is occasional and disposable. One-off checks, quick curiosity measurements, a single dimension you will use in the next five minutes and never again. It is pre-installed, it is fast, and adding another app would gain you nothing.
And if you are still surveying the whole category rather than choosing between these two, our overview of what a modern AR measuring app can do is the broader starting point.
Here is something most comparison pages will not tell you: on an iPhone, Apple Measure and Measure Tools are built on the same underlying AR technology — Apple's ARKit. We will not claim Measure Tools is universally more accurate than Apple Measure, because that would not be honest. The difference between the two apps is in the toolset and the workflow, not in some secret measuring engine.
What actually determines AR measuring accuracy, in either app (our guide to AR accuracy covers each of these in depth, with fixes):
In good conditions, AR measurements from either app are excellent for planning, shopping and estimating. For work where an error costs real money — cutting expensive material, ordering custom-built pieces, anything structural — confirm the critical dimensions with a tape measure. No phone-based AR app, ours included, should be treated as construction-grade.
No. Apple Measure is pre-installed on iPhone and iPad only, and Apple does not offer it for Android. The closest equivalent is a cross-platform AR measuring app: Measure Tools offers the same category of AR measuring on both iOS and Android, so a mixed iPhone/Android household or team can use one app.
The part that overlaps with Apple Measure is, yes: basic AR measuring is included in the free, ad-supported experience with no usage limits — along with a free bubble level and a free DPI-calibrated onscreen ruler. The subscriptions only unlock the extra toolset: the full set of measuring modes, unlimited measurement folders, floor plans, and true-size 3D furniture planning. So trying it, or replacing Apple Measure for everyday measuring, costs nothing.
On iPhone, both apps are built on Apple's ARKit, so raw measuring accuracy is comparable — we won't pretend otherwise. The difference is the toolset and workflow: dedicated measuring modes, saved measurements with photos, floor plans and true-size 3D furniture. On any AR app, accuracy improves with good light, textured surfaces, steady movement and LiDAR hardware.
At the time of writing, Apple Measure offers screenshots and copy-to-clipboard, plus a recent-measurements list on some devices — measurements don't persist as organized records. Measure Tools saves measurements as photos with the dimensions overlaid, organized into folders (two folders free; unlimited with the Measurements subscription).
No — Apple Measure measures lines and detected rectangles. Floor plans on iPhone come from dedicated apps: in Measure Tools, Floor Plan mode (3D Planning tier) walks you through marking corners, setting wall heights and adding windows and doors, then shows the result in 2D and 3D.
Apple Measure answers "how long is this?" Measure Tools is built for everything that comes after: the saved records, the room math, the floor plan, the furniture that has to fit. It is free to download — put it on your phone, measure a real room, and see whether the extra toolset earns its place.
