An easy-to-use accurate audio/visual tuner for your guitar.

Provides a simple interface to visually check whether the pitch for each string is low or high, and lets you "see" the pitch change as you wind/unwind the string tuning machines. Tuning has never been easier.

Shows exactly how many cents (1/100ths of a semitone) a note is out-of-tune.

- Extremely accurate - within 1 cent (1/100th of a semitone) of each note with sub-second response time.
- Developed in Austin, Texas, the "Live Music Capital of the World".
- Use the standard tuning E-A-D-G-B-E or one of many alternate tunings: regular tunings such as Minor Third, special tunings such Drop D, open tunings such Open C, lower tunings, higher tunings.
- Adjust pitch incrementally from 400 to 480 Hz or up/down a half/full step from A440. (The International Organization for Standardization specifies the frequency for the note A in the treble stave as 440 Hz. ISO 16:1975).
- Tap to hear an accurate note if tuning by ear instead of using visual tuning.
- Enable/disable Auto-string-detect (not recommended for noisy environments).

Pros and cons of Guitar Tuner! app for iPhone and iPad

Guitar Tuner! app good for

Ive had trouble using other peoples real tuners - I can usually get closer by eat, but this one worked like a dream! Vienna philharmonic matches my harmonica perfectly. This app purchase has been my best gamble yet!!!
First time guitar owner here. I tried about 7 tuner apps, growing more and more frustrated, until I found this. After an hour of trying the others, this app had me in tune and playing in about 2 minutes flat. Can not recommend thus app enough!
Ive never had a tuning app that worked well before. Id choose this over an actual tuner for the sake of convenience.
This guitar tuners much better than my standalone guitar tuner. Its definitely worth the price. Its insane how accurate it is.
Works great, and I especially appreciate the ability to tune by listening to the notes this app provides, and also tune by the notes the app picks up from you playing your own guitar.
Imagine buying a cheap tuner at a music store... Itll cost many times more, itll do that same thing but not a well, youll have to carry it everywhere you go, on and on and on. I am very happy with this app.

Some bad moments

I had a problem, when i using this app its just automatically close.. I have ipod touch 5th gen. Updated to ios7.2 - You guys need to fix this..
This used to be an awesome tuner but now the tuner doesnt detect the strings at all. Because of the new operating system? Fix it please.
I really like this tuner!!! Its better/easier then the tuner I got when I bought my guitar!
Finally something that does what you think it will. So easy to use. Totally intuitive. Thanks!
Worth the money! Easy, intuitive, and accurate - which as a novice/beginner I needed. Still my most used app for guitar.
I found my standard digital tuner to be far more accurate! Kinda want my money back!
