Accelerometer Analyzer is a free Android application developed by MOBILE TOOLS. It is a powerful vibration meter tool that makes use of the accelerometer sensor present in Android devices. The tool can show vibrations in real-time and save vibration data into SD card (zip files also supported). It can also calculate the Root Mean Square (RMS) of the vibrations, which is useful for self-made DRONE calibrations. Moreover, the tool provides a configurable sound alarm that can detect earthquakes or if somebody opens the door when you sleep.

It is recommended to use the battery charger when it works for a long time. However, the application comes with ABSOLUTELY NO WARRANTY. The tool is a must-have for those looking to analyze vibrations and keep track of their vibration data.
