Description
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).

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.
Quick way to check tuning I use it to check trombone intonation also guitar
The excellent design and performance of this app makes using it transparent.
I went back to a headstock tuner— way more accurate.
Outstanding tuner. I would recommend it to any Guitarist 👍
Love it! Pay $2.99 and be done with it. No annoying ad videos or pricey monthly subscriptions. This is all the guitar tuner you need.
Way, way better than the alternatives, especially with respect to alternate tunings but even just for getting standard dialed to within a cent or two
This is a very good app but if you don’t remove it from memory after you done using it, it will drain your battery.
Appreciate the app. Always tuned by ear, but getting older and tuning abilities a little off 😊. This is perfect for me!
Finally A quality tuner that lets you tune to the slightest degree even in a noisy room, without some lunatic nutjobs’ sick idea of “advertisement” popping up every three seconds to hinder your mad skills. Thanks
