HarmonicAlly

A complete harmonica toolkit. Look up chords, find the right harp, identify keys, manage your collection, and explore alternate tunings. Free, no purchases inside.

Play More. Guess Less.

HarmonicAlly™ puts a complete set of harmonica tools in your pocket. It’s built for harmonica players, but it speaks guitar, ukulele, bass, piano, mandolin, banjo, and more. Look up a chord, find the right harp for a song, identify the key of a progression, and keep track of every harmonica you own - all without leaving the app.

WHAT’S INSIDE

QuickGuide™ Look up any chord or scale, then see how it lays out on a different instrument. Useful for harmonica players, and just as useful for guitarists, ukulele players, and pianists who want a fast cross-instrument reference.

HarmoniFinder™ Tell it your song’s key and feel, and it tells you which Lee Oskar harmonica to grab. Honest rankings, no padded results.

Key Detective Tap the chords you’re hearing and the app figures out the key. Hand the result to HarmoniFinder™ and you’re playing.

My Collection Track the harmonicas you own. Useful at gigs, useful at home, useful when you’re trying to remember whether you actually own a Low F before you click “buy.”

Tuning Workshop Explore the four Lee Oskar tunings, mix and match reed plates between them, and try custom tunings adapted from a wide library, including blues, country, folk, Celtic, jazz, and world music presets.

Learn & Care Practical tips for playing positions, troubleshooting common issues, and keeping your harmonicas in good shape. Toolkit, not teacher.
