Simple Guitar Tuner

This application is just a simple guitar tuner that aims to be really easy to use and contains no annoying ads. All you need to do is run it and start tuning your guitar. It will automatically detect which string are you tuning and how close you are to your perfectly tuned sound. It's that simple!
Application supports numerous tunings. What allows it to be so simple and accurate is complicated underlying technology. Years of mathematical and computer science developments were encapsulated in this simple app.
