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).

  • Really great

    By Brain Mentalblock
    This is the nicest tuning app I've used. Easy to read and accurate. Tip: Lay your phone on top of the guitar above and to the left of the sound hole, resting against the lower end of the fretboard. You'll get a great signal.
  • Simply the best

    I don't need tuners for my guitar, mandolin, banjo and ukulele. This app covers them all, and I don't have to remember where I put it after I last used it. OK, I can't tune my piano or Sousaphone with it, but every musician should have this app.
  • Killer app

    Once I found this tuner app I quit looking further. Easy, more than standard tuning, and I enjoy watching the oscilloscope action. Thanks
  • Pretty Good!

    For my Amatuer ear, it is pretty accurate & I like using my izpjone to tune verse other implements.
  • My favorite tuner!

    By Charlie Senn
    I use this all the time to tune my guitar and it's quick and effective! Way better than one of those tuners you buy at like Guitar Center.
