SCREENSHOTS
Mobile rangefinder for smartphones and tablets
What is the height of 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 models mobile devices simple calibration required.
The accuracy of calculations is one of the reasons to download Smart Measure for Android for free. The application determines the height of the object and the distance to it, based on the rules of trigonometry. As a result, all final measurements are as reliable as possible. Users can fix 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 just one touch. For precise aiming at an object, a cross is displayed on the gadget screen. It must be pointed at the top point to measure the height and at the bottom 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 in a stylish and modern way, using Material Design. The interface is Russified, 11 other languages are supported. Management is made as simple as possible, so it's easy to deal with the application.
Paid content
You can download Smart Measure for Android for free from the link at the bottom of the application page. The program is ready to use. There are no time limits in it, but there are advertisements for monetization. There is also a paid Pro version of the application, which currently costs 85 rubles. There are no ads in it, and the functionality is expanded by supporting portrait orientation, camera zoom, the ability to calculate the area of an object, and some other options.
In this review, we will consider 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, a speedometer, a 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 according to their popularity in Play market. Testing was carried out on a smartphone Honor 5A.
The idea of this type of application is very simple, it 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 Russian. But it has more than a million downloads in 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 reference 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, while it is actually more than eleven). For calibration, you can use a regular ruler or some object of known length. But if there was no such object or ruler 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 US, EU, Canadian, Australian, British or Swedish coins are suitable for calibration.
Both the metric system of measurement and the imperial one, in inches, are available to the user. Supports night mode to save battery.
The program can remember the measurement by writing it to the history. This is convenient when you measure several items at once. But for some reason, when testing, the application did not save the history.
⇡ "Ruler: Smart Ruler"
The application was developed by Smart Tools, which has 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. AT free version the application will show ads to the user, and in the paid application, in addition to the on-screen ruler, there is a protractor, a set of templates for determining the thread pitch and profile (thread gauge), a level and other tools.
After launching the application, the ruler, as in the 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, Ruler: Smart Ruler allows you to measure objects 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 impossible to save the measurement results here. But the application allows you to measure an object longer than the screen - for 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 ads, and saving the measurement results will not be available.
For calibration, you need to put a real ruler on the screen and move the on-screen ruler so that the divisions match. To measure the length, you can use either side of the screen as a regular ruler, put an object on the screen and manually set the start and end points of the reference, as well as measure the length and width of a rectangular object at the same time.
As in other applications, you can measure objects in centimeters and inches. The application supports night mode and screen rotation.
Creating tools of this type usually requires the presence of 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 the smartphone, which they receive from the gyroscope.
AR Ruler App
The AR Ruler application was developed by the Belarusian company Grymala. To measure the distances and sizes of objects, the program uses augmented reality (AR) technology.
The program can measure the linear dimensions of objects (in metric system or inches), the distance from the device camera to a point on the plane, angles on 3D planes, the area or perimeter of an object (both rectangular and polygonal and round), the volume of three-dimensional objects, the length of the path taken with a smartphone, the height of objects (for example, a doorway or furniture). There is also a simple on-screen ruler in the application.
AR Ruler requires the ARCore library from Google, which can be installed on smartphones with Android 7.0 and higher. To improve the accuracy of measurements, the developer advises taking three or more measurements and focusing on the average value.
⇡ Measure
The app 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 snapshot of the measurement, as well as copy the results to the clipboard.
⇡ "Rangefinder: Smart Measure"
The program was developed by Smart Tools, as well as the already reviewed application "Ruler: Smart Ruler". "Range Finder: Smart Measure" can measure the distance to an object and its height. The principle of the program is based on trigonometry. The presence of 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 best measurement accuracy, the smartphone must be held at a height of 30 cm less than your height.
The program provides for 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 the real ones by no more than 5%. According to reviews in Google Play it can be judged that not in all cases the measurements are so accurate. Perhaps it depends on the smartphone model.
Applications of this type use the gyroscope and accelerometer of the device to determine the angle of deviation of any side of the smartphone or its back surface.
⇡ "Laser level - leveling tool"
The Laser Level - Leveling Tool application was created by EXA Tools, which has developed several other similar applications. The program includes three tools - a laser level, a bubble level and an inclinometer. The application is completely Russified.
For more accurate measurements, the app may need to be calibrated. To do this, you need to find a perfectly horizontal surface and calibrate the application data on it. However, it is not easy to understand how to do this - the program does not contain appropriate prompts, which users also complain about in the comments on the Play Market.
During testing, the application showed pretty good results. Of course, building a house using only this level is not worth it, but in some everyday matters, for example, when installing a cauldron on a makeshift hearth in the forest or a washing machine in an apartment, a smartphone can help a lot. In addition, the capabilities of the application clearly depend on the operation of the smartphone's sensors - on the Play Market, reviews about 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 one directly in the application.
⇡ "Building level"
"Construction Level" is the development of the already mentioned NixGame. The application contains two tools - a level and a ruler. However, the ruler here is just additional functionality, the corresponding application of the same developer has about more possibilities. The program is fully 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 work, since the device will not lie on the surface stably (this remark is also true for all other programs of this type).
The level can be used in two ways. The first involves aligning 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 on one of the sides of the smartphone. In this case, you need to try so that the lines showing the angle of deviation from the calibrated horizontal coincide with it.
When the ideal horizontal is reached, the application can report 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).
In addition to the level, the program has only one possibility - its calibration. Moreover, the developer claims that it will be needed only 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 declare 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 level view can be fixed so that the interface does not change when the smartphone moves.
The program is able to report the achievement of the horizontal with a sound signal. If necessary, the level can be calibrated.
The paid version differs from the free version by the absence of ads.
Even a simple smartphone can do a good job of replacing tools such as a ruler or level, showing fairly accurate measurement results. To fully use your smartphone as a tape measure, it is best to have a device with Android 7.0 and higher, but the accuracy will still not be up to a centimeter. As metal detectors, smartphones don't seem to be very good, but perhaps the reason is the weak magnetic sensor on the tested device.
Convenient and easy to use, the Moasure app is all in one: 300m/1000ft tape measure, ruler, protractor and goniometer (angle measurer). Just move your phone from one point to another and Moasure will measure the distance, height difference or angle between the two points.
No tape measures, ribbons, laser beams or photographs. Instead, Moasure uses the same technology as space rocket guidance systems - the accelerometers and gyroscopes in your phone - allowing you to accurately measure the distance you've moved your phone. Moasure is the result of the development of rocket science!
Moasure can measure the length, width and height of objects, as well as the dimensions of rooms and even the distance between rooms. It is the only application that maintains its accuracy at distances greater than 10m/30ft thanks to the unique multi-step Moasure measurement mode. There are 5 different measurement modes covering external dimensions, internal dimensions, height difference and angles.
It can measure around obstacles as if they weren't there, so it's great for measuring the size of a room. You can also measure on any surface. Display of results in metric or imperial units is available. Distance accuracy is typically between 1% and 3%, depending on the smartphone model. Angle accuracy is better than 1 degree.
Moasure is a simple app on your smartphone, available anytime, anywhere. There is no need to connect to the Internet or look for a ruler, tape measure or laser in the toolbox or in the kitchen to measure. Roulette is now always at your fingertips. Moasure uses proprietary technology to produce the most accurate results of any motion measurement application. You can buy Moasure - Smart Roulette in the Google Play store for 189.00 rubles.
