Things people ask first.
Is it really free?
Yes. No in-app purchases, no subscription tier, no premium unlocks. The full toolkit is in the app from the first launch.
Do I need to make an account?
No. There are no logins, no sign-ups, and no usernames. The app works the moment you open it.
Does it need the internet?
No. HarmonicAlly™ works fully offline. Useful on stage, in basements, and on flights.
What languages does it support?
Twenty languages including English, Spanish, French, German, Italian, Japanese, Korean, Hebrew, Farsi, and more. RTL languages are supported.
Do I have to play a Lee Oskar harmonica?
No. HarmonicAlly™ works with any diatonic harmonica. The Tuning Workshop is tuned to the four Lee Oskar tunings because that's what the app was built around, but the rest of the toolkit is brand-agnostic.
I don't play harmonica at all. Is it useful?
QuickGuide™ handles 11 instruments — guitar, ukulele, bass, piano, mandolin, banjo, fiddle and more. Plenty of non-harp players use it as a fast chord and key reference.
Where can I report a bug?
Email Support. A real human reads each one.
Is this an official Lee Oskar product?
Yes. HarmonicAlly™ is published by Lee Oskar Enterprises, Inc., the company behind Lee Oskar Harmonicas.
From Lee Oskar Harmonicas.
Making harmonicas for musicians since 1983.
