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).




  • Excellent

    By Professor Oller
    This is a much better way of tuning then the unit I bought and keep in my guitar case. It seems much more accurate and I like being able to listen to the tone I am tuning to.

    This app hasn’t been updated for iPhone X (over a year old!!!) and it looks terribly on my screen. Please update.
  • Easy to Use, Very Accurate

    For a tuner on a phone, iPad, etc, it does its job very well. It’s especially handy being able to have the selected string play what it should sound like!
