If you're looking to Download VioTuner on your Chromebook laptop Then read the following guideline.

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.
