## What is Vibroscope?

"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 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. It is also possible that the accuracy error will accumulate if the vibration is too large, it may not be appropriate to display the measured value.
- While driving a car or operating machinery, please do not use this app for safety.
- The logarithmic scale graph displays very small numerical value, so it may be affected by noise and temperature error in your environment or time fluctuation of sensor calibration.
- Log data can be transferred from an iOS device to a Mac or PC using the iTunes File Sharing feature. MacOS Catalina and later can share files between an iOS device and a Mac using the Finder. 

Please visit our iOS app support page for more information on this app.

### 5/5 — Good app.

*2023-01-30*

Works as advertised. Nice graphics. Support answered me in one hour on a Sunday afternoon!!!! Not integrated with “share to files” system on the iPhone.  Only way to see the log file is to plug into a Mac with a charging cable and then use finder. Not very handy. I would much rather use airdrop. but plug in is doable as long as you have a Mac. Is much better than the “free” competitors that start asking for money for even the most basic features.

### 5/5 — 乗り物の動きを解析するには最適です！

*2021-04-23*

私はクルマの乗り心地や運転操作の解析に使っていますが、とても重宝しています。
鉄道マニアの方も各車両の乗り味などの解析に使ったら面白いかも知れませんね。
サポートも丁寧で迅速、動作は非常に安定していて大満足です。

### 3/5 — F F T

*2018-12-27*

水平方向の F F T解析機能を掲載して下さい。

### 3/5 — 保存が出来ない

*2016-08-07*

iPhone 6では何度保存しても、エラーが出て出来ない。
iPhone 5cでは問題が無いですが。
何の問題かわかりません

### 1/5 — A bit useless

*2016-07-27*

No vertical scale on FFT page, and vibration limited to <50Hz. So, generally pretty useless
