GhostVibe Lite app for iPhone and iPad

Seismograph / Seismometer vibration detection.

Detect vibration and movement using the sensors built into your smart phone or tablet. Features include:

+ 4 different visualisations, including seismograph/seismometer, bulls-eye, vortex and meter.
+ Adjustable sensitivity.
+ No adverts or in-app-purchases. No internet connection needed. No unnecessary permissions required.

INSTRUCTIONS
Place your device on a flat, solid surface. Any vibration or movement will be detected so it is useful to detect earthquakes, seismic activity, etc. Your device must have accelerometers to work with GhostVibe Lite - which most mobile Apple devices have.
Live data is visible on the screen and is updated roughly 30 times a second.
Tap the screen to pause the app and access the settings.
You can choose one of 4 visualisations for the live vibration data.

LITE VERSION
This lite version of GhostVibe does NOT contain logging. The full version is available from the store and includes:
+ Saves daily logs which you can view later.
+ Export daily logs in CSV format to other apps, e.g. your favourite spreadsheet application.

SENSITIVITY
You can adjust the sensitivity of the displayed data by tapping the cog icon.
Dragging the bar left will make it less sensitive, dragging the bar right will make it more sensitive. Some devices have more sensitive sensors than others.

PERMISSIONS
This app does not show adverts. It does no contain any in-app-purchases. It does not require an internet connection. The only permission it needs is for storing your settings.
