## What is Gyro?

This is a scientific tool. This app allows for high-precision monitoring and recording of the different sensors embedded on an iPhone.

Supported sensors include:
Gyroscope (rotation rate along 3 axes @50Hz)
Accelerometer (acceleration along 3 axes @50Hz)
Magnetometer (magnetic field along 3 axes @50Hz)
Barometer (air pressure @~1Hz)

This app features "live windows" where you can easily see past motion data.
In addition to a nice visual layout, this app provides a "record" feature, which will record the currently selected motion data and export it as a CSV.

Future updates will include landscape orientation support, and maybe even some "MultiPeer" data aggregation.

## Key features

- High-precision sensor monitoring
- Gyroscope, accelerometer, magnetometer, barometer support
- Live motion data visualization
- Record and export sensor data as CSV
- 50Hz sampling rate for key sensors

### 1/5 — Might be useful if ...

*2021-03-18*

Looks to be a useful app except seems to crash when exporting to local notes file or to OneDrive.

### 5/5 — Smooth like butter

*2018-07-14*

Truly is a beauty.  Good UI, good raw sensory data.  Csv output is nice, although wish there was a configurable polling interval.

### 4/5 — Does what it says - Perfect!

*2018-05-25*

Nice tool for seeing raw data from some of your phone’s sensors.

Keyboard bug on settings page.

### 1/5 — Does not function on iPhone SE

*2018-05-10*

May windows are not proportional so you can’t tap the record button and when you go to settings and try to type you can get out of keyboard mode to save and continue, it has been rendered useless on my phone

### 5/5 — Nice app and nice clean interface

*2018-02-08*

Great app with some great features and nice smooth and easy to use interface! One thing I have noticed is that when recording the data , the logging seems to stop when the screen is locked. Would be useful if it could continue regardless of screen lock or not.
