Quick , simple and easy to use

I’m a pro player and this tuner works well. It’s quick and when I’m rushing (most of the time) I find it very accessible and useful. The ads don’t bother me. Some folks are complaining, ignore the ads that are at the bottom of the screen and don’t interfere with you striking a note at all.

The most useful tool I have.

I usually don’t write reviews but I can’t pass on this. Some people have minor issues with the app, like with the ads and whatnot, but coming from someone who’s owned this app for years now, I have to say I use it a lot. Even though I play guitar just about everyday, I’m horrible when it comes to owning and keeping tuners. This app has been my go to whenever I’ve had to tune when I’m practicing or getting ready to jam. It has all the standard tunings, such as standard (duh), half step, and drop D, but it even includes some other tunings that are not so common, such as double drop D, new standard, and open A minor. This app has helped me not just keep my guitar in tune, but open up new and interesting tunings to use in my playing, especially once I got use to playing in standard. I would recommend anyone who wants a simple yet useful tuning app to look no further than this one.

This app works well with just one minor downfall in my opinion. The notes do not sustain long enough for you to even accurately tune your string. If this feature could be improved it would make this app one of the better ones out there. Every time I grab my guitar and press the note/string desired to tune the note quickly dies out. They should offer that or let the note auto-repeat somehow.
