Ruler AR vs. Apple Medición: comparación directa y honesta
Apple's built-in Measure app is free and pre-installed. So why install anything else? Here's a feature-by-feature breakdown of where Apple stops and where Ruler AR keeps going.
Apple's Measure app launched alongside iOS 12 in 2018. It uses the same ARKit framework that every third-party measuring app relies on, so the raw accuracy is roughly identical. The differences are elsewhere, in what you can do with measurements after you take them, and which scenarios the app actually handles.
What Apple Measure does well
- It's free and pre-installed. Zero friction for a one-off measurement.
- Decent at single distances. Tap two points, see the result. Works.
- Auto-detects rectangles. Point at a picture frame or a piece of paper, it'll highlight the rectangle and offer to measure all sides.
- Auto-detects people's height. If a person is fully in frame, the app draws a line to the top of their head and reads their height.
- Has a basic level. Two-axis bubble level, OK for hanging a frame.
Where Apple Measure stops
- No project history. Every measurement is a screenshot or it's gone.
- No PDF export. You can share screenshots, not formatted documents.
- No angles. Just linear distance.
- No area. You can't draw a polygon for square footage.
- No 3D room scan. Even on LiDAR iPhones, Apple Measure doesn't use the depth sensor for room scanning.
- No manual floor plan builder. On non-LiDAR iPhones, there's no fallback workflow.
- No project folders. No way to group "kitchen measurements" together for a renovation.
- No annotations or notes. Just naked dimensions.
- No accuracy modes. No Touch Mode for sub-cm precision; the only AR mode available.
What Ruler AR adds
| Capability | Apple Measure | Ruler AR |
|---|---|---|
| Length / distance | yes | yes |
| Height (auto-detect for people) | yes | yes |
| Bubble level | basic | 3 modes (vertical, horizontal, free) |
| Angle measurement | no | yes, AR protractor |
| Area / polygon | no | yes, Square mode |
| 3D LiDAR room scan | no | yes, RoomPlan |
| Manual floor plan (no LiDAR) | no | yes |
| Touch Mode (sub-cm precision) | no | yes |
| Project folders | no | yes |
| Photo + note annotations | no | yes |
| PDF export | no | yes |
| USDZ 3D export | no | yes (with LiDAR) |
| Material calculator (paint, tile, etc.) | no | yes |
| Project sharing | screenshot only | PDF, 3D, Messages, AirDrop |
When Apple Measure is enough
- You just want to know how tall something is, right now, once.
- You don't care about saving the result.
- You don't need angles, area, or any kind of room plan.
- You don't want to install anything.
When you'll outgrow Apple Measure within a week
- You're planning a renovation and need to measure multiple rooms.
- You're shopping for furniture and want to share dimensions with someone else.
- You measure things for a living (contractor, designer, real estate, insurance).
- You want a measured floor plan, not just individual dimensions.
- You want to attach notes and photos to specific measurements.
- You need to send a professional-looking report to a client or contractor.
The honest take
Apple Measure is a fine ten-second tool. It's not designed to scale, it's a quick "Settings" app, not a workflow. Ruler AR (and other full-featured AR measuring apps) exist because the moment you take more than one measurement that matters, you need somewhere to put them, a way to share them, and tools beyond linear distance.
Keep Apple Measure for one-offs. Install Ruler AR (free, no subscription required for the basics) for everything else. The moment you need to measure two things in a row, you'll know which one to open.
