## What is CaliberTune?

CaliberTune turns your iPhone or iPad into a pocket timegrapher for mechanical watches.
Simply place your watch near the microphone and CaliberTune analyzes its escapement to display the key measurements used in watch regulation.
Measure:
• rate in seconds per day
• balance amplitude
• beat error
• movement frequency in BPH
• measurement stability
The timegrapher also displays the tick and tock trace in real time, with a presentation inspired by professional watchmaking instruments.
Save your sessions to compare different watch positions, monitor changes after regulation, or keep a history of your measurements.
CaliberTune works entirely on your device:
• no account required
• no Internet connection required for measurements
• no measurement data sent to a server
Compatible with iPhone and iPad.
For best results, measure in a quiet environment and place the watch as close as possible to the microphone without touching the device.
