HotPaw Guitar Tuner

A strobe tuner is "the most accurate type of tuner" according to Wikipedia. The HotPaw Guitar Tuner provides 6 precision Strobe Tuners for your guitar. Fast. Accurate. Noise resistant. See your notes also appear on a keyboard image and a musical grand staff also, as a great music learning aid. Uses the built-in mic on your Mac, or an external microphone.

With 6 simultaneous strobe tuners, you don't need to wait for your room or recording studio to become quiet enough. You don't need to wait for a tuner to lock onto each note. You don't need to wait for a needle to finish moving. If you're really good, you don't even need to tune one guitar string at a time. With multiple strobe tuners, you can see if one string shifts in frequency while tuning another. You can also see if plucking a string hard on your guitar causes the notes to "bend".

Just watch the waterfall waveforms overlaid on each string. When the waves for a particular guitar string synchronize or line up vertically and stop leaning and shifting left (flat) or right (sharp), you are precisely in tune with an internal equally-tempered digital oscillator.

8 alternate tunings (Standard EADGBE, Drop D, DADGAD, etc.) are supported.

Also available are the HotPaw iChromatic tuner for OS X in the Mac App Store, and the inTuna Strobe Guitar Tuners for iPhone and iPad in the iOS App stores.

What's New in Version 1.1.7

Customer Reviews

Works well now

This seems to be working well now - although the lowest sounding E string is not as clear visually.

Money well spent

Great App. easy to use and great for alternative tunings.
