About this app

Pano Tuner listens, finds your pitch, and shows you exactly how far you are — sharp or flat — clearly enough to trust. Simple to open, accurate enough to rely on, and a favorite of players and teachers for years.

One precision engine, almost any instrument. From the lowest bass string to the top of a piccolo or harp, Pano Tuner tracks the note the instant you play — and shows both the note and its exact frequency, in hertz and cents.

MADE FOR REAL MUSICIANS
• Fast, sensitive, accurate — reacts immediately and holds steady.
• Tune almost anything — guitar, bass, ukulele, violin, viola, cello, harp, brass, woodwinds, voice, and folk & world instruments.
• Match your ensemble — set concert-A (e.g. A=442) to your group or a historical pitch.
• Read notes your way — A B C, Do Re Mi, fixed-Do, German H, and more.
• A clear, readable meter and a clean, distraction-free design.

BEYOND EQUAL TEMPERAMENT
Most tuners know only one tuning. Pano Tuner includes nine historical and microtonal temperaments — Equal, Pythagorean, Just, quarter-/third-/sixth-comma meantone, Kirnberger III, Vallotti, and Werckmeister III — and lets you create and save your own. Made for harpsichord, organ, early music, and anyone tuning beyond the modern standard.

ALSO
• Play a clean reference tone for any note.
• Adjustable tolerance, so "in tune" means what you need it to mean.

Free to use. A one-time purchase removes ads — temperaments and every tuning feature are always free.

Best free guitar tuner app available. It opens directly to the tuner, no sign-ins or extra fluff, just straight to the point: open app – tune guitar – close app – play guitar. The free version has a tiny banner ad that's barely noticeable. It also has many of the features you'd expect from a guitar tuner app like transposing and frequency control. It's just so refreshing to use an app that isn't begging you to sign-up, subscribe, or demanding the your email and personal information.

Former 5 Star review: Easy to use. Great for alternate tunings. Update: Sadly, the new version of the free app is terrible. Visually, it has no style and is completely generic. Practically, it is harder to read than the old one. There is no simple way to exit the app, an annoying app trend. Obviously, they want you to pay now for what was free last year by just downgrading the free product to something no one would want.

I love this tuner. It's simple, it's easy to see, and it does exactly what I need it to do without a bunch of buggy junk. The only thing that threw me was that the default readout was "backwards" from what I was used to ("flat" was to the right), but I was able to change that in the settings, no problem. It's solid, reliable, straightforward, and great for old eyes ... 5 stars, and thanks, developers!
