"Vibroscope" is a measurement tool for analyzing vibration by using the iPhone's acceleration sensor in realtime. It allows you to monitor by visualizing the very low-frequency vibration such as inaudible by ear.This app can be intuitively detected an acceleration amount, that displays the two-axial coordinates in the horizontal direction and the time-axis waveform in the vertical direction. "Vibroscope" is also equipped with the ability to analyze the frequency components of the low-frequency vibration by the FFT analyzer."Vibroscope" can be measured by determining the horizontal or vertical direction to suit the attitude of the iPhone, so as to be available in a placement of the floor and desk or Handheld.Acceleration measurement data will be also saved as a log file, so you can use it as Data Logger by acquiring a file from "iTunes File Sharing".Utilization example:- In cases such as car traffic, to analyze the vibration and frequency components on the floor and walls. - To measure the howling level such as audio equipment.- To detect the vibration and acceleration of train or automobile.- To check your sense of body balance by sensing of the horizontal direction of the body swinging. Features:- Measurement of vibrations : acceleration values (m/s/s)- Real-time display : the horizontal direction - the two-axial vector plane graph, the vertical direction - the time-axis waveform.- 3-axis composite acceleration display (yellow line on the time-axis waveform). - Display of the peak acceleration level along X, Y, Z, 3-axis composition. - Switching of the sensor sampling period : Fast, Slow.- Timer measurement : 10 seconds to 1 hour.- FFT Analyzer for vertical direction, with vertical vibration sensation correction. - Display of the peak frequency in the FFT mode.- Display of Location information with privacy settings of "Location Information display SW" function.- Snapshot of the measurement screen : Capture the measurement results and Time-stamp with Location information to Camera-roll.- Data Logger : X-axis, Y-axis, Z-axis, saved in a text file (UTF8) . It saves the measurement data, Time-tamp and Location information to LOG file. It can be exported by using "iTunes File Sharing". Precautions:At the time of the first access to Location and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app can not access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Photos or Location Services".The location information is permitted only during the use of this application, external data transmission is never done. Position information display on the measurement screen in the MAIN mode, you can be disallowed in the privacy settings. This app does not support to the background operation, so it needs to set on "Never" in the iOS setting, "Settings > General > Auto-Lock" for a long time operation.Notes:In general, there is variation and accuracy error by individual terminals and sensor devices of the iPhone, so this app does not recommend the use in the formal measurement. There is also a possibility that the accuracy error is accumulated if the vibration is too large, it may not be appropriate measurement display. During in car driving or operating machinery, please do not use this app for safety.
