Smart Tools for Android

Smart Tools is a smart application package for you, including 5 extremely useful and handy toolkits to help you perform calculations, measurements quickly, easily and accurately.

These 5 toolkits include:

• Smart Ruler Pro - Tool to measure length, angle and slope
• Smart Measure Pro - Tool to measure distance, height, width and area
• Smart Compass Pro - Provides compass, metal detector and GPS
• Sound Meter Pro - Sound intensity and vibration measurement tool
• Smart Light Pro - Provides a flashlight to provide light for the device

Watch the introduction video for Smart Tools for Android below:

Program overview:

Click on Length & Angle , there will be a set of rulers appear, these rulers are very familiar and easy to use. They all support multiple points to help you get the best measurement results. Please watch the video below to see how this ruler is all-powerful:

Not only measure the size of regular objects, with the Distance tool, you can measure the height and width of an object.

Explain the instructions in the image above:

• Check the distance of the camera from the ground (in the image of Android is 1m75 high, and the camera is at 1.5m).
• To measure the distance: use the camera to aim at the position of the girl's shoes, and touch the camera icon to get the result.
• After determining the distance, use the camera to aim at the top of the girl's head, and touch the camera icon to get the height of the girl.
• Note: The android uncle and the girl must stand on the same plane.

Next is the metal detector (in the Compass section), which is very new and extremely interesting. Combined with the magnetic field sensor device built into the phone, the program can identify the magnetic field generated by surrounding objects. As we all know, the magnetic field (EMF) level in the normal environment is about 49μT (490mG, 1μT = 10mg).

When metal is detected around, the μT will increase. So, this application will help you trace the negative power lines in the wall and the metal lurking in the ground . rare)

The usage is very simple, open the detectors, and move it around, then the magnetic values ​​will change, and you will know where the metal is.

The accuracy of this function depends on the device you are using, sometimes the interference from electromagnetic waves from TV, computer, etc. To make the sensor function work better, when starting this function, Point the phone up in the air and follow the picture of the 8 (to eliminate the interference).

Next we will study the Compass compass in the program toolbox: This is a compass that works by magnetic sensor mechanism. It still works correctly whether you rotate the screen horizontally or vertically. In addition, this compass also incorporates the camera and GPS navigation, so be assured, when you have this compass in your hand, you will never get lost. When the compass is working incorrectly, check the surrounding magnetic field.

The final function of Smart Tools is a vibration and noise determination tool ( Sound & Vib ).

Sound Metter (determine sound level): this function may not work properly, because the program uses the phone's microphone to capture noise in decibels, while the microphone is Phone manufacturers adjust to get the best quality voice. As for the Vibrometer (vibration determination) function, you can measure the phone vibration, body vibration or seismic measurement, etc.

Sometimes, you need to monitor the vibration level of your surroundings, to determine the stability of the infrastructure. Nowadays there are many 'jagged' constructions, if you are sitting in the office or somewhere, turn on the Vibrometer and you see it vibrates differently than usual, please prepare the posture.
