Working tools that can be replaced with a smartphone. Construction level on the phone - how to install? Bubble level for android

In this review, consider the screen rules, roulettes, levels and metal detectors for Android. Sensors and various smartphone elements allow you to create other tools - for example, a compass, speedometer, a sound meter. But due to the fact that in everyday life, such tools are rarely used, they are not included in the review.

The selection of applications of each category was made by their popularity in Play Market.. Testing was carried out by smartphone Honor 5a.

The idea of \u200b\u200bapplications of this type is very simple, there is no need for any special sensors at all. A ruler is displayed on the screen that needs to be calibrated for real values, and it will be ready for use.

⇡ Ruler

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

After starting the application, two rules appear on the screen - on the left and above. With their help, you can define the dimensions of a small object placed on the screen. The reference point is in the left upper corner Screen and can not be moved.

In order for measurements to be correct, the ruler must be calibrated (for example, after starting the program determined the screen length equal to nine centimeters, while it is actually more than eleven). For calibration, you can use a conventional line or any item known length. But if such an item or ruler did not turn to hand, then an ordinary credit card or coins are suitable for calibration, the dimensions of which are known for the program. Unfortunately, the sizes of Russian coins the program does not know, and only coins of the USA, EU, Canada, Australia, Great Britain or Sweden are suitable for calibration.

The user is available as a metric measurement system and imperial, in inches. Supported night mode For saving charge.

The program can remember the measurement by writing it down. It is convenient when measuring several items at once. But when testing the application, the story for some reason did not save.

⇡ "LINE: SMART RUURER"

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

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

Unlike Ruler, in the line "LINE: SMART RUURER" application, it is possible to measure items, putting them on the middle of the screen and indicating the beginning and end. However, simultaneously measure the length and width of the subject in the free version of the application. It is impossible here and save the measurement results. But the application allows you to measure the subject of greater length than the screen - for this you can move the left line together with the subject.

Units of measurement can be like inches and centimeters.

⇡ "LINE"

The application is issued by the Russian developer of NIXGame, which offers users and other similar work tools. The free version will have to put up with advertising, and the saving measurement results will not be available.

For calibration, it is necessary to attach a torch to the screen and shift the on-screen line so that the divisions coincided. To measure the length, you can use any side of the screen as a conventional ruler, put an object on the screen and manually set the start point and end point, as well as measure the length and width of the rectangular item simultaneously.

As in other applications, it is possible to measure objects in centimeters and inches. The application supports night mode and screen rotation.

To create tools of this type, it is usually required to have a recondeled reality library from Google - Arcore. But there are applications that can determine the distance to the item using trigonometry laws using for this the angle of inclination of the smartphone, which they receive from the gyroscope.

Ar Ruler App.

The AR Ruler application is developed by the Belarusian company GRYMALA. To measure distances and sizes of objects, the program uses augmented reality technology (AR).

The program can measure the linear dimensions of objects (in the metric system or inches), distance from the device chamber to the point on the plane, the angles in the 3D planes, the area or the perimeter of the object (both rectangular and polygonal and round), the volume of three-dimensional objects, the length of the path made by smartphone, height of objects (for example, door opening or furniture). There is an application and a simple screen line.

For work AR Ruler requires Arcore Library from Google, which can be installed on smartphones with Android 7.0 and above. To increase the accuracy of measurements, the developer advises to conduct three dimensions and more and focus on the averaged value.

⇡ Measure.

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

You can take a snapshot of the measurement, as well as copy the results obtained in the clipboard.

⇡ "Ranger: Smart Measure"

The program has been developed by Smart Tools, as the "Line: Smart Ruler" application already reviewed. "Ranger: Smart Measure" can measure the distance to the 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 the object and its height, it is necessary first, aiming the cross on the base of the object, click the button on the screen, and then do the same in relation to the top point. Then the program will calculate the distance to the object and its height. For better accuracy measurement, the smartphone must be kept at an altitude of 30 cm less than your growth.

The program provides manual calibration: from the user you need to measure the real distance to the item and its height and indicate how much percent of the values \u200b\u200bmeasured by the program differ from valid. When testing, the program showed quite quite good results, differing from real no more than 5%. According to V. Google Play. It can be judged that not in all cases of measurement are so accurate. Perhaps it depends on the smartphone model.

Applications this type Use a gyroscope and an accelerometer of the device to determine the angle of deviations of any side of the smartphone or its rear surface.

⇡ "Laser Level - Level Tool"

The application "Laser - Leveling Tool" was created by Exa Tools, which developed several more 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, it may be necessary to calibrate the application. To do this, you need to find the perfect horizontal surface and calibrate the application data on it. However, it is not easy to understand how to do this is not easy - there are no appropriate tips in the program, for which users in the comments on Play Market are complaining.

When testing, the application has shown quite good results. Of course, it is not worth building a house with only such a level, but in some household matters, for example, when installing a cauldron on a homemade focus in the forest or washing machine In the apartment, the smartphone can help well. In addition, the applications of the application clearly depend on the work of the smartphone sensors - on Play Market, the program reviews are mostly diametrically opposed.

The paid version of the program is distinguished only by the lack of advertising, go to it from the free right in the application.

⇡ "Construction level"

"Construction Level" - the development of the already mentioned nixgame. The application contains two tools - level and ruler. However, the line here is simply an additional functionality, the corresponding application of the same developer has aboutmore opportunities. The program is completely Russified (and supports 14 more languages).

As well as in previous applicationThe level can be calibrated by putting the smartphone on the perfect horizontal surface. True, if the back cover is slightly convex, then the exact calibration may not work, since the device will not lie on the surface steadily (this remark is true and for all other programs of this type).

The level can be used in two ways. The first suggests to align the object by putting the smartphone with a back cover on its surface. In this case, it is necessary to ensure that the bubble in the center of the screen accurately fell into a limiting circle. The second method involves alignment on one side of the smartphone. In this case, you need to try to lines showing the angle of deviation from the calibrated horizontal coincided with it.

When achieving an ideal horizontal application can report it sound signal.

⇡ "Bubble Level"

Simple app without additional features. On the main screen - the three bubble icon, allowing to level the surface on the side of the smartphone, along the bottom or on the rear surface (immediately in several planes).

In addition to the level, there is only one possibility in the program - its calibration. Moreover, the developer declares that it will be needed only in cases where the manufacturer of the smartphone has not calibrated the device properly. This remark seems true for other applications, just for some reason the developers do not declare about it. At least, when testing all applications of this type without calibration, there was no difference in the accuracy of measurements. Paid version differs from the free only advertising.

⇡ "Level"

According to the functionality, the level application is similar to the "bubble level", the low difference is that it is automatically able to determine which side of the smartphone is monitored (side, top, bottom or back cover) And show the appropriate level on the screen. Needed species Levels can be fixed so that when the smartphone is moving, the interface has not changed.

About the achievement of the horizontal program is able to inform the sound signal. If necessary, the level can be calibrated.

Paid version differs from the free absence of advertising.

Even a simple smartphone can be not bad to replace such tools such as a ruler or level, showing quite accurate measurement results. To fully use the smartphone as a roulette, it is best to have a device with Android 7.0 and above, but the accuracy will still not be up to a centimeter. As metal detectors, smartphones, it seems, are not very good, but maybe the reason is in a weak magnetic sensor on the test device.
