Hi , I'm new to this forum. I love guitar and have developed a new guitar tuner app - "Tuna'Droid guitar tuner". It is based on a simple interface and I've tried to do it accurate and easy to use. Your reviews and feedback will help me improve this app. It works on a lot of devices but there are some incompatibility issue. Here is the link : https://play.google.com/store/apps/details?id=com.rinie.tunadroid And a screenshot : Thank you .
