Guitar Tuner+ is a simpler way to tune your guitar. It automatically hears which string you are tuning and expands that area for maximum visibility. When you are done tuning that string, it's last tuned position is saved on screen so you can see your tuning progress. Tap any note name to play a reference pitch to tune by ear.

Needs a feature

I would have given this app five stars if it had a chromatic tuner or let the user create a tuning.

Bad Tuner

Won't automatically pick up the guitars sound. Have to put my phone very close to the sound hole. Had to mess around with the background noise filter in order to have it pick up the guitar. When I started tuning it the level kept bouncing back and forth and wasn't giving me an accurate reading. I'll just keep using my GuitarTuna app instead. Easy off the bat. Don't want to spend time calibrating or figuring out a tuner, rather than playing guitar.

I'm sorry it sounds like you were having issues with Guitar Tuner+! This tuner is designed for extremely fine tuning, and because of this in a noisy environment the needle may jump due to additional tones it picks up in the room. In these cases please set the background noise filter to 'high'. This should solve your issue.
