I love pretty much everything about this app. I like the spectrum type diagram style for each string, and how the frequency shifts from pluck to termination of the vibrations. Love the massive selection of alternate tunings, the interface, etc. The perfect little app. For best results when not plugged in, I position the iphone so that the bottom is resting on the headstock to pick up the vibrations. I've played around with different placements and this gives me the best results. Holding the phone with your left hand securing the bottom part (with the mic) firmly against the guitar's wood while adjusting the tuners with my right hand gives me the best results. For my headless guitars, I hold the phone on the metal plate and that gives even better resonance. Since the sound of a string in a noisy environment can be hard to capture by all tuning apps, I've found that they work even better by vibrations, where I think the buzzing of the resounding wood against the phone matches the sonic frequency of the string through the microphone. That's my theory anyway. The fact that vibrations work better than remote sound capture would probably support my theory. FYI, if you tap the little (i) icon, you can choose auto detect string. I don't use it, but mention it because I think a lot of new users might be confused at first because the default setting requires that u first choose the string to be tuned. So u might sit there plucking a string and wondering why nothing is happening. Select the string and then pluck the note unless u toggle the auto-detect function. Oh, and heads up. If you're plugged in and press the string for a reference tone, TURN DOWN YOUR VOLUME so u don't blow out your eardrums and jump through the ceiling. Has caught me off guard a couple times :) developer should default sound down to low levels to protect user hearing when headphone is detected. 5 star app. Get it. - **5★ · My Favorite · October 24, 2019** — First of all, to all those complaining it hasn’t been updated - it doesn’t need to be! It works great, who cares if it fills the entire screen on my iPhone 11? There’s a lot out there, but this is always my go-to. Super simple and easy to use, it lets you know just how close or far off you are. Love the interface. Great work! I’ll be using this for years to come. - **5★ · 10 years+ later, still amazing · February 1, 2026** — Great app, thanks for all you do. I just learned about open tuning and of course this app supports that. I also just learned about playing 415hz, which this app supported me in learning more about and tuning into these different ways to play. Thanks for keeping it going. ## About 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). ## Questions about this app ### What are Guitar Tuner! iOS app's download statistics?
