"Vibroscope" is a powerful vibration analysis tool that uses the iPhone's acceleration sensor to measure various vibrations in real time. It allows you to monitor and visualize very low frequency vibrations that are inaudible to the human ear.

This app intuitively detects acceleration amounts and displays the two-axial coordinates in the horizontal direction and the time-axis waveform in the vertical direction. It can measure by determining the horizontal or vertical direction to suit the attitude of the iPhone automatically, so as to be available on the floor and desk or handheld.

"Vibroscope" is also equipped with FFT analyzer that can analyze the frequency components of very low frequency vibrations. The measurement data can also be saved as a log file, so you can use it as a vibration data logger.

Application Examples:
- Analysis of the amount of acceleration and frequency components of the floor and walls during car traffic.
- Measurement of howling vibration of audio equipment, etc.
- Detection of acceleration and vibration of trains and automobiles.
- Body balance check (horizontal body shaking detection).
- Measurement of vibration acceleration during earthquakes, etc. (displayed value x 100 [GAL])

Features:
- Measurement of vibrations (Main): acceleration values (m/s/s)
- Real-time display: the horizontal direction (X-Y) - 2-axis vector plane graph, the vertical direction (Z) - the time-varying graph.
- Display scale switching of vibration acceleration graph (Linear/Log): Linear - linear scale display, Log - logarithmic scale display.
- 3-axis composite acceleration display (Compo)
- Peak level value display (Peak)
- Switching of acceleration display (Instant/Average): Instant - instantaneous acceleration, Average - average acceleration per second.
- Scaling of measurement display range
- FFT analysis for 3-axis directional and composite acceleration, with peak frequency (FFT)
- FFT graph display control (Axes/Axis-1/Axis-2)
- Switching of sensor sampling period (Slow/Fast): slow, fast
- Axis direction (Axis): Swapping the axis direction on the graph display during operation.
- Measurement timer function: 1 sec to 1 hour
- Start delay timer function: 0 - 20 sec
- Reference level setting in FFT mode: 1e-6m/s/s, or 1e-5m/s/s
- Snapshot of the measurement screen (Snap): Capture the measurement results and Timestamp to "Photos".
- Data Logger: X-axis, Y-axis, Z-axis, saved in a text file (UTF8). It saves the measurement data, timestamp to LOG file.

Important settings:
- At the time of the first access to Photos after installing the app, you will be asked permission to access them from the iOS system. If you did not enable this setting on this time, it cannot be access from the app by privacy restrictions of the iOS. Please enable slide switch of the app in the access permission of the iOS setting, "Settings > Privacy & Security > Photos".
- This app does not support to the background operation, so it needs to set on "Never" in the
