its not exactly what it says but..

Not a automatic tuner, ya know a lot of people who have to have automatic or electric tuners instead of leaning it by ear yes you will be a little disappointed. But if you can match the tone of a electronic string to the one on an actual guitar and they sound the same then you will like the app. It does not have the arrow/needle/ dot/ what ever else there is tuning your guitar. It has the string names, and sounds you tune it by that sound if you can not do that, its something you need to learn down the road as a guitar player maybe not now but it needs to be learned.
