📌 BOSS Tuner is the only app that is ad-free and most importantly the only one that can be set to 'Hz' in the standard version. Version 1.2.0. This is the most honest app yet. Even Fender only offers 'Hz' adjustment in the Pro paid version, they are obsessed with money and don't care about musicians and music. Thank you Japanese B○SS (Roland)!

[Tip use an external microphone] I was expecting much less, such as some kind of pay wall, only being able to use less than half of the features, things like that, and yet I was actually surprised & impressed by this app. It definitely exceeded my expectations. I even kinda like the catalog that it comes with. Definitely could do with out it and it wouldn't be much of a loss in any way. I just hope that they keep it updated, since we're stuck with it. I also have it on more than one device. BOSS

This is pretty sharp, spot on accurate. I installed it after losing my clip on guitar tuner. I can tune by ear alone but like to check it is perfectly tuned, using an electronic device. To feel secure. I thought this would be hard and unreliable but it was easy, very accurate and trustworthy. No excuses for out of tune guitar playing. Bad enough playing wrong notes/chords, without adding out of tune guitar and probably off key, out of tune voice. Guitar in tune gets one fundamental thing right,
