WARNING: very easy to run out of trial notes on badly out of tune pianos, due to confusing/bad UI

This seems like a pretty featureful and effective app. Unfortunately I never got my piano through even a complete first pass tuning before it disabled due to the trial note limitation—500 notes would seem totally adequate except due to it constantly changing notes from auto-detection, I blew through 300 notes in ~2 octaves of tuning alone (upper registers are extra flaky)…. I don’t know if the instructions are badly written or I’m dumb, but even setting to “manual” pitch changing did not stop it from jumping to adjacent pitches (most strings in this piano were over 50 cents off, so it was constantly swapping pitches). In the end, I never completed a single full pass before the app disabled itself…. Note that it’s possible you can avoid eating up your trial notes by going into “Pitch Check” mode first *before* beginning a tuning session, so that you can get every string within 50c before fine tuning/measuring inharmonicity/etc—I only discovered this by wandering through the help screens later on (but annoying each one is only on its related screen, and the “tutorial” is extremely brief and confusing). But since even that function is disabled now, I’m not certain how/if it works or if it really avoids burning trial notes…. So sadly right now I have a still badly out-of-tune piano (90% of it within 20c maybe, after settling, but it sounds horrible) and a now-useless app… so I can’t verify whether the tuning it (will) produced is quality or not. It’d have been *extremely* helpful if there was a lock feature on the pitch change control (no auto-detection) OR if the startup screens emphasized not to jump straight into the tuning session and guided the user to a more useful/less frustrating pathway. Anyway, just a warning to others thinking about taking this app for a spin.

PiaTune - best app for the price!

Most of the professional apps for piano tuning can do just fine on excellent pianos. The real challenges for apps are often the smaller pianos, and PiaTune outshines the rest due to both the measuring and graphing functions that allow the user to customize the tuning calculation. The developer has added specific enhancements that work well even with spinets. Combined with an effective pitch adjustment process has made getting the best sounding tunings out of so many different sized instruments during a regular tuning appointment.
