SCREENSHOTS

Mobile rangefinder for smartphones and tablets

How tall is this architectural monument? How many meters to this road sign? To answer these questions, having only a smartphone at hand, you need to download Smart Measure for Android. With this application, any mobile device can easily play the role of a rangefinder.

Features and Features

Calibration – there are mobile devices for which the development team has already carried out all the necessary settings. But most mobile device models require simple calibration.

The accuracy of calculations is one of the reasons to download Smart Measure for Android for free. The application determines the height of an object and its distance based on the rules of trigonometry. As a result, all final measurements are as reliable as possible. Users can record them by taking a screenshot of the screen, for which the program provides a special button.

Ease of use - you can measure the height of an object and the distance to it with literally one touch. For precise targeting of an object, a cross is displayed on the gadget screen. It must be pointed at the top point to measure height and at the bottom point to find out the distance.

Ease of use and design

Since this application is part of the Smart Tools package, its design is consistent with the compass, distance meter and other programs from the same developers. It is decorated stylishly and modernly, using Material Design. The interface is Russified and supports 11 other languages. The controls are made as simple as possible, so understanding the application is easy.

Paid content

You can download Smart Measure for Android for free using the link at the bottom of the application page. The program is ready to use. There is no time limit, but there are advertisements for monetization. There is also a paid Pro version of the application, which currently costs 85 rubles. There are no advertisements in it, and the functionality has been expanded to include support for portrait orientation, camera zoom, the ability to calculate the area of ​​an object and some other options.

In this review, we will look at on-screen rulers, tape measures, levels and metal detectors for Android. Sensors and various elements of a smartphone allow you to create other tools - for example, a compass, speedometer, sound level meter. But due to the fact that such tools are rarely used in everyday life, they are not included in the review.

The selection of applications in each category was made based on their popularity in the Play Market. Testing was carried out on the Honor 5A smartphone.

The idea behind this type of application is very simple and does not require any special sensors at all. A ruler is displayed on the screen, which needs to be calibrated to real values, and it will be ready for use.

⇡ Ruler

The application was developed by Xalpha Lab and does not support the Russian language. But it has more than a million downloads on the Play Market, so the program can be considered one of the most popular lines for Android.

After launching the application, two rulers appear on the screen - on the left and on the top. With their help, you can determine the size of a small object that fits on the screen. The origin point is in the upper left corner of the screen and cannot be moved.

In order for the measurements to be correct, the ruler must be calibrated (for example, after launching the program, the screen length was determined to be nine centimeters, whereas it is actually more than eleven). For calibration, you can use a regular ruler or any object of known length. But if such an object or ruler is not at hand, then an ordinary credit card or coins, the sizes of which are known to the program, are suitable for calibration. Unfortunately, the program does not know the sizes of Russian coins, and only coins from the USA, European Union, Canada, Australia, Great Britain or Sweden are suitable for calibration.

The user has access to both the metric and imperial measurement systems in inches. Night mode is supported to save battery.

The program can remember the measurement by recording it in history. This is convenient when you measure several items at once. But during testing, the application for some reason did not save the history.

⇡ “Ruler: Smart Ruler”

The application was developed by Smart Tools, which created a whole package of working tools for smartphones - a compass, a metal detector, a sound level meter, and so on. The program is completely Russified. In the free version of the application, the user will be shown advertising, and in the paid version, in addition to the on-screen ruler, there is a protractor, a set of templates for determining the pitch and profile of the thread (thread gauge), a level and other tools.

After launching the application, the ruler, as in Ruler, must be calibrated. But this can only be done manually by measuring the length of the screen and entering the data in the calibration field.

Unlike Ruler, the Ruler: Smart Ruler app lets you measure items by placing them in the middle of the screen and specifying a start and end. However, you cannot simultaneously measure the length and width of an object in the free version of the application. It is not possible to save measurement results here. But the application allows you to measure an object longer than the screen - to do this, you can move the ruler to the left along with the object.

Units of measurement can be either inches or centimeters.

⇡ "Ruler"

The application was released by the Russian developer NixGame, which offers users other similar working tools. In the free version, you will have to put up with advertising, and saving measurement results will not be available.

To calibrate, you need to attach a real ruler to the screen and move the screen ruler so that the divisions coincide. To measure length, you can use either side of the screen as a regular ruler, place an object on the screen and manually set the start and end points of the reference, and also simultaneously measure the length and width of a rectangular object.

As in other applications, you can measure objects in centimeters and inches. The application supports night mode and screen rotation.

Creating these types of tools typically requires Google's augmented reality library, ARCore. But there are applications that can determine the distance to an object using the laws of trigonometry, using data on the angle of inclination of the smartphone, which they receive from the gyroscope.

AR Ruler App

The AR Ruler application was developed by the Belarusian company Grymala. The program uses augmented reality (AR) technology to measure distances and sizes of objects.

The program can measure the linear dimensions of objects (in the metric system or inches), the distance from the device’s camera to a point on a plane, angles on 3D planes, the area or perimeter of an object (both rectangular, polygonal and round), the volume of three-dimensional objects, path length image taken by the smartphone, the height of objects (for example, a doorway or furniture). The application also has a simple on-screen ruler.

AR Ruler requires the ARCore library from Google, which can be installed on smartphones running Android 7.0 and higher. To increase the accuracy of measurements, the developer advises taking three or more measurements and focusing on the average value.

⇡Measure

The application is developed by Google itself. Like the previous one, it allows you to measure the linear dimensions of objects, the distance from the camera to the object (like a tape measure), the height of objects, and so on.

You can take a photo of the measurement and also copy the results to the clipboard.

⇡ “Rangefinder: Smart Measure”

The program was developed by Smart Tools, like the already reviewed “Ruler: Smart Ruler” application. "Rangefinder: Smart Measure" can measure the distance to an object and its height. The operating principle of the program is based on trigonometry. The ARCore library is not required, so this “roulette” can be used on smartphones with Android 4.0 and higher.

To measure the distance to an object and its height, you must first aim the cross at the base of the object, press the button on the screen, and then do the same for the top point. Then the program will calculate the distance to the object and its height. For better measurement accuracy, the smartphone should be held at a height 30 cm less than your height.

The program provides manual calibration: the user is required to measure the actual distance to the object and its height and indicate by what percentage the values ​​​​measured by the program differ from the actual ones. During testing, the program showed quite good results, differing from real ones by no more than 5%. Based on reviews on Google Play, one can judge that the measurements are not so accurate in all cases. This may depend on the smartphone model.

This type of application uses the device's gyroscope and accelerometer to determine the angle of deflection of any side of the smartphone or its back surface.

⇡ “Laser level - leveling tool”

The Laser Level - Leveling Tool app was created by EXA Tools, which has developed several other similar apps. The program includes three tools - a laser level, a bubble level and an inclinometer. The application is completely Russified.

For more accurate measurements, app calibration may be required. To do this, you need to find a perfectly horizontal surface and calibrate the application data against it. However, it is not easy to understand how to do this - the program does not have appropriate hints, which users also complain about in the comments on the Play Market.

During testing, the application showed pretty good results. Of course, it’s not worth building a house using only this level, but in some everyday issues, for example, when installing a cauldron on a makeshift fireplace in the forest or a washing machine in an apartment, a smartphone can be a good help. In addition, the application's capabilities clearly depend on the operation of the smartphone's sensors - on the Play Market, reviews of the program are mostly diametrically opposed.

The paid version of the program differs only in the absence of advertising; you can switch to it from the free version directly in the application.

⇡ "Construction level"

“Construction Level” is a development of the already mentioned NixGame. The application contains two tools - a level and a ruler. However, the line here is simply additional functionality; the corresponding application of the same developer has O greater opportunities. The program is completely Russified (and supports 14 more languages).

Just like in the previous application, the level can be calibrated by placing the smartphone on a perfectly horizontal surface. True, if the back cover is slightly convex, then accurate calibration may not be possible, since the device will not lie firmly on the surface (this remark is also true for all other programs of this type).

The level can be used in two ways. The first involves leveling the object by placing the smartphone with the back cover on its surface. In this case, it is necessary to ensure that the bubble in the center of the screen exactly falls into the bounding circle. The second method involves alignment along one of the sides of the smartphone. In this case, you need to try to ensure that the lines showing the angle of deviation from the calibrated horizontal line coincide with it.

When the ideal horizontal position is reached, the application can indicate this with a sound signal.

⇡ “Bubble level”

A simple application, without additional features. On the main screen there are three bubble level icons that allow you to level the surface along the side of the smartphone, along the bottom or along the back surface (in several planes at once).

Besides the level, the program has only one option - its calibration. Moreover, the developer states that it will only be needed in cases where the smartphone manufacturer has not calibrated the device properly. This remark seems to be true for other applications, but for some reason the developers do not state this. At least, when testing all applications of this type without calibration, no difference in measurement accuracy was found. The paid version differs from the free version only in the absence of advertising.

⇡ "Level"

In terms of functionality, the “Level” application is similar to the “Bubble Level”, with the slight difference that it is automatically able to determine on which side of the smartphone the surface is being leveled (side, top, bottom or back cover) and show the corresponding level on the screen. The desired type of level can be fixed so that the interface does not change when the smartphone moves.

The program can notify you when the horizontal line is reached with a sound signal. If necessary, the level can be calibrated.

The paid version differs from the free version in the absence of advertising.

Even a simple smartphone can be a good substitute for tools such as a ruler or level, showing fairly accurate measurement results. To fully use a smartphone as a roulette, it is best to have a device with Android 7.0 or higher, but the accuracy will still not be down to a centimeter. Smartphones don't seem to be very good as metal detectors, but perhaps this is due to the weak magnetic sensor on the device under test.

"Rangefinder: Smart Measure" is a useful Android application that will help you measure the distance to an object and its height. You just need to point the camera of your mobile phone at the desired place, and the program itself will do the rest and produce a ready-made result. Just remember to correctly calibrate the sensors on your device, and then the accuracy of the readings will be very high.

The scope of application can be very diverse: from professional activities to entertainment purposes.

The interface of the "Rangefinder: Smart Measure" application is quite intuitive, and navigation to the necessary points is quick. The hint system will fully explain the purpose and rules for using different functions. To access the main menu, you need to touch the icon in the upper left corner. It will present some sections and settings.

Feedback will give you the opportunity to contact the developers with any questions about the operation of the application.

You can purchase the advanced version for a small amount of money. The graphic design is designed in a pleasant and simple style, and the color schemes leave a good impression. Some actions have been dubbed. Full optimization allows the image to be displayed normally on different screen sizes.

The creator of this project is the young studio "Rangefinder: Smart Measure", which specializes in useful mobile products. It provides high-quality technical support, releasing new versions with bug fixes and additional features.

Operating system version 4.0.3+ is required to run. You can download the free Android application "Rangefinder: Smart Measure" for your smartphones on our website, to do this you need to follow the appropriate link.
