## What is VioTuner?

My daughter Uli started her violin lessons at school, and she had nothing to tune her violin with. So I created this small app for her.

Just press the string number button and tune to the sound.

The notes in the app are played by Yamaha Disklavier Pro a professional piano. Thank you to Roberto Gordo Saez for making this sound font available under Creative Commons license.

I noticed one of the most popular complains about similar apps is too short note play length. So I've added a possibility to choose for how long to play a note between 1 and 10 seconds.
