Chromatic tuner. Guitar tuner. Fast and precise rotating strobe tuner. Also see your notes appear on a keyboard image and a musical grand staff as a great music learning aid.

The display of visual high-contrast strobes will enable rapid and extremely accurate tuning of your musical instruments. More familiar-looking tuning dials and fine tuning meters are also available and visible below the two strobes.

Make a strobe stop spinning, and your note will be in tune. Spinning slightly clockwise, and this indicates that your note is slightly sharp. If the strobe is spinning too fast to see, then your note is way out of tune.

The strobe on the left does automatic note detection. The strobe on the right is set manually to one note, which is useful if there is too much background noise for automatic note detection to function properly. The popup button above the strobe on the right can be used to select the note, or you can use the up/down cursor keys to adjust the note for tuning.

For high background noise situations, a multi-strobe mode that displays strobes for all 12 chromatic notes, simultaneously, can be helpful.

For those who prefer tuning dials and fine tuning meters, those are visible below the two strobes.

The Concert A frequency can be customized in Preferences.

The approximate working range is from 2 octaves below to 2 octaves above Middle C, depending on the microphone being used and the volume settings.

For your iPhone and iPad, please see the HotPaw inTuna Strobe Guitar Tuners and iChromatic HD tuner in the iPhone/iOS App store.
