• Help

Level bubble is an application for android that will allow you to save money on a special device. Indeed, why spend it at all if you always have a phone with you, and it has a gyroscope? Why pay twice? But even if you already have a ruler with a level, you should still install the level application, because due to the human factor, you can always lose it.

Before working with it, do not forget to check the phone’s gyroscope; to do this, select the gyroscope settings function in the settings, and place it on a surface that is absolutely flat, in your opinion, or simply on a standard surface. Just make no mistake, because the landscape tower is a wonderful example of the human factor... Next, place either side of the phone as close to the object as possible, so you can measure the angle or slope of the object. To measure the angle, first place the phone on a flat surface.

Among the features of the application:

• Independence in calibration of either party.
• Regardless of whether you need tangents, degrees or percentages, you can easily measure all this!
• A convenient sound effect in the “Level” application, which allows you to understand that the calibration was successful even without looking at your phone!

How to install a building level (spirit level and bubble level) on a smartphone and phone?

The measuring level is a useful tool for professional builders and ordinary people. In the age of technology, engineers have come to the conclusion that a bubble level (spirit level) will be a useful feature for smartphone owners. We'll tell you why you need a building level in your phone, how to install and use it?

Why do you need a building level on your phone?

This tool is mainly used in the construction and repair industry. Using a level, horizontal and vertical surfaces are determined to identify deviations. This procedure is required in many cases, from the construction of a building to the installation of a wall shelf.

You can also use a spirit level to set up tripods for photographs and level paintings on the wall. The device is used to measure the surface in the manufacture of a desk or billiard table. In household cases, the level helps to level the refrigerator or washing machine.

Obviously, not everyone has such a tool, although it can always come in handy. In this situation, the building level installed in the phone comes to the rescue. To determine a flat surface, the application uses and, and sometimes the gadget’s camera is also used. We are talking about three programs that will replace the professional construction level on a regular smartphone.

Laser level

The “Laser Level” has a bright and pleasant design that imitates working with a real construction tool. The program functions similarly to a professional bubble level, measuring the surface from different angles. The application has a built-in accurate clinometer that determines vertical and inclination angles.

The program provides data in different units. Here you can also adjust the measurement accuracy and lock the orientation. "Laser Level" equipped with digital and analog indicators, with the help of which it becomes even more convenient to work with the level.

The application captures both near and far objects. The laser level determines the angle of inclination of roofs, buildings, mountains, and a TV simply hanging on the wall. Thus, the application is suitable for construction and finishing work as a digital and laser meter.

Benefits of the program:

• Bright design.
• Easy calibration.
• Laser and digital meter.
• Different units of definition.
• High fixation accuracy.
• Lots of additional features.

Building level

The application is simple and multifunctional. It uses primitive graphics without any frills, but this does not prevent the spirit level from being used for its intended purpose. Using the program, the inclination of the surface is measured, the angle is calculated with a hold function, and the zero level is equipped with a sound indication. Measurements are carried out in three modes. Among other functions, there is a ruler and tape measure.

The mobile level is perfect for repair and finishing work, as well as for other everyday situations that require precise determination of the surface and angles. Another advantage of the application is quick and easy calibration.

Advantages:

• Simple and intuitive interface.
• Several measurement modes.
• Easy calibration.
• Measuring angles.
• Additional functions.

Bubble level

The application simulates a classic bubble level with a limiter. The realistic design of the program replicates a professional tool. The smartphone screen shows a curved glass tube in which a special flask filled with liquid is installed. Based on the position of the air bubble floating in the liquid, the inclination of the measured surface relative to the horizontal is determined.

The program fixes the surface in the horizontal and vertical plane, and also determines the degree of deviation from the X and Y axis. Bubble level is easy to configure, has many additional options and is easy to manage.

Advantages:

• Realistic graphics that simulate a real instrument.
• Easy to measure surface.
• Fast and easy calibration.
• Multifunctionality.
• Circular level indicator measurement.

How to calibrate a building level on your phone?

Typically, building level applications are configured by default by engineers. But there are cases when the calibration was carried out incorrectly and the program needs to be re-configured. In this case, you need to do the following:

1. In the application settings, select “Calibration”.
2. Place the gadget on a flat surface and click on the “Install” button.
3. To return to factory settings, click Reset.

Bubble level(spirit level) is a measuring instrument designed to indicate the horizon. With it, you can easily and simply assess the conformity of a surface to a horizontal or vertical plane, and the tool is also able to measure the degree of surface deviation.

A bubble level is simply indispensable for any builder, and is also useful on the farm to determine the level of inclination and level something evenly on a vertical or horizontal surface. In order to measure the slope angle, you just need to touch your smartphone to the object and thanks to the built-in orientation sensors on the screen you will be given the result whether the object is level or not on the surface. A spirit level is a traditional modern level meter; this device is a slightly curved glass tube, inside of which there is a flask filled with liquid and an air bubble, and it is by the position of this air bubble that one can judge the angle of inclination. The app will try to simulate a real tool and help you measure the angle of a surface relative to a vertical or horizontal plane.

This type of construction tool is used in construction as well as photography. With proper and proper use of the device, you will be able to evenly position pieces of furniture, for example: clearly hang a picture on the wall, or place a curtain rod above a window, or measure the level of a billiard table.

Features of the Bubble Level app on Android:

• modern measuring level;
• fast and easy calibration;
• shows slope or angle;
• switching X and Y axes (for some devices);
• clear interface;
• horizontal or vertical slope measurement.

The program will turn your phone into a level with which you can check the inclination level without resorting to additional tools.

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 instruments - 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 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, 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.
