Other notable options for Android
In addition to those mentioned, there are versatile tools that adapt to different needs:
- Google Maps: It's not a real-time measurement app, but it's the ultimate tool for measure distance in Google Maps Outdoors. It allows you to set a starting point and plot routes to know the exact route between multiple stops.
- AR Ruler: A powerful application that uses the augmented reality (ARCore) It measures distances, angles, areas, and volumes. It allows you to mark points on real surfaces, although it requires an AR-compatible device.
- EasyMeasure: Ideal for those who need a simplified interface to measure the distance between two objects or from the user to a specific target using the camera lens.
- Ruler: A basic but effective tool that functions as a virtual ruler on mobile, ideal for small objects where the size of the device is not an impediment.
LiDAR and Augmented Reality: the new frontier of precision
On the other hand, if you're looking for something more advanced and precise, you should check out these other distance measurement apps that use LiDAR sensors and Augmented Reality (AR), which deliver incredible results. LiDAR (Light Detection and Ranging) uses laser light pulses to map the environment in 3D with millimeter precision, far surpassing simple trigonometry. You can learn more about Time-of-Flight (ToF) in cameras to better understand these technologies.
ARPlan 3D: Ruler
AR Plan 3D is a highly innovative application that utilizes the LiDAR sensor included in the multi-sensor cameras of new smartphones and augmented reality (AR). This allows it to measure lengths quickly and with significantly greater accuracy than previous apps. It acts as a virtual measuring tape or ruler applied to real-world surfaces such as rooms, furniture, etc., enabling the instant creation of 3D maps.
It's an exceptional tool for measuring millimeters, inches, centimeters, meters, yards, and feet. It also includes specific functions for measuring windows and doors, calculating perimeters and square footage of floors and walls, which is extremely useful for estimating the necessary building materials , such as the amount of paint or varnish. Floorplanner allows you to work with and easily share the 3D and 2D maps you create.
MagicPlan
Rounding out the list of distance measurement apps is MagicPlan, which can take measurements and gather information about terrain , as well as create sketches. It's very easy to use and can work with both 2D and 3D interior plans, with the ability to add photos, 360° images, text notes, custom forms, and markers to create structured reports.
This app is one of the most popular worldwide and also uses LiDAR, gyroscopes, and AR Core to maximize accuracy. It offers its features for free, allowing users to create and share renovation projects. It even includes the Estimate tool , which quickly calculates budgets and prices. A key feature is its compatibility with external laser distance meters from professional brands such as DeWalt, Bosch, Stabila, Leica, Stanley, and WDM, elevating it to a superior technical level.
Measurement solutions for iOS (iPhone and iPad)
Apple's ecosystem has integrated measurement very seamlessly, especially in the Pro models that feature dedicated LiDAR hardware. These are the best options for iPhone users:
- Apple Measurement: It's the pre-installed native app. It turns your phone into a digital measuring tape capable of calculating the dimensions of real-world objects and automatically detecting rectangles (like doors or pictures). Its greatest value is... immediacy.
- Apple Maps: Like Google Maps, it is the ideal tool for measuring distances between geographical points, optimizing travel plans or tourist routes.
- Distance Measure and Ruler AR: Third-party applications that enhance the use of Arkite to obtain more accurate results by scanning the camera, allowing you to easily measure any object in the environment.
Technical comparison: Mobile app or professional laser distance meter?
It's crucial to understand that, while apps have improved dramatically, there's a clear difference between estimating and certifying . AR and camera-based apps are excellent for quick sketches, initial quotes, or quick answers to questions, but they have limitations:
- Environment dependency: Accuracy varies depending on lighting, surface quality (reflections or very dark surfaces confuse the sensors) and device calibration.
- Human factor: In trigonometry apps, a slight tremor in the hand can vary the measurement by several centimeters.
- Professional Use: For technical work, such as energy certifications or architectural surveys, the use of a laser distance meter. tools like Leica DISTO Plan o Bosch MeasureOn They do not attempt to replace the laser, but rather enhance it, synchronizing the actual measurements of the physical device with a digital plane via Bluetooth.
Specialized tools for complex cases
There are solutions that deviate from the usual camera pattern:
- Polycam: More than a measurement app, it's a tool for space captureIt creates 3D models using photogrammetry or LiDAR, allowing measurements to be taken directly on the captured model. It is ideal for architecture and expert reports.
- Moasure: It uses its own device that measures based on the motion and inertiaIt is the best option for measuring irregular perimeters in gardens or plots of land where the laser cannot find a reference wall.
- RoomScan Pro: Focused on creating quick interior floor plans, especially efficient in furnished homes where it is difficult to draw straight lines with the camera.
For those who need more options, don't miss our detailed selection of measuring apps for Android.
Choosing the right tool depends entirely on the objective: for quick reference at home, Augmented Reality apps are amazing; for measuring an outdoor plot, GPS and maps are key; and for professional construction or renovation projects, combining a LiDAR sensor or a laser distance meter synchronized with a plan management application is the only way to guarantee real technical accuracy.
