Open E Guitar Tuner
This easy-to-use app will allow you to quickly and accurately tune your guitar to Open E. This app uses REAL guitar sounds for your tuning pleasure, not those generic computer generated pitches.
This is a really fun tuning, and is great for both standard and slide playing!
To use, simply press the button that corresponds to the string you would like to tune. When pressed, each note will play 6 times. To move to the next note, simply press the next button and the prior note will stop sounding.
Enjoy and happy tuning!
If there are other tunings you would like to see on the Android Market leave a comment and I'll do my best to get one put together.
