Magnetic Field Detector
This application detects the nearby emf generated by metal. It uses your phone’s built in magnetic sensor.
Just Open the app a check the stats. When any metallic object is near you will see the fluctuating reading go stronger.
To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern.
Sound Meter & Noise Detector
Sound meter is an indispensable tool for your daily life, no matter what you do, where you stay, it is a practical noise detector to help you avoid noise pollution that harms your hearing and affect your rest. Our sound meter app can provide accurate decibel data and show you how the decibel goes.
Get noise data more comprehensively and more accurately:
Minimal, average and maximal decibel
Real-time decibel in dial and graph
Levels of noise
Calibrate before use for precise data
Review measurement histories
Customize your sound meter
Save audio file while measuring
Set decibel warning when the value is higher than the preset one
Open the sound or vibrate for the warning
Apply the black or white theme
Other features of sound meter:
Re-start measuring
Suspend recording
Rename, share and replay the recording
Indicate the measuring duration, time and status
Notice:
1.To get an accurate decibel of sound with this decibel meter (noise meter), please calibrate before use (because the performance of the microphone will be different for each device).
2.Adjust the decibel according to your experience or calibrate with a real sound meter device for comparison. (Because we couldn’t estimate the different decibel between devices, we do not provide a specific solution.)
3.To avoid unnecessary loss, please SAVE your recording before exiting the sound meter app
4.If the recordings are not saved, you cannot replay the measurement.
Vibration Meter
This app uses acceleration sensor to measure vibration or an earthquake, and it shows a reference as a seismic detector (seismograph).
The measured values are related to Modified Mercalli Intensity scale (MMI). If it is inaccurate, you can calibrate it so that maximum value is about 10-11.
Please use the result only for reference because Android devices have a wide variety of performance and sensitivity.
