Great tool for fun and professional use

I first used N-track tuner 5 years ago when I forgot my regular guitar tuner and found that my iPod could be used as one. The spectrum analyzer can provide a visual feedback to observe how plucking the string at various points results in different harmonics. I also used the app in my HS Physics class for observing different frequencies and harmonics of tuning forks and sound generating experiments. Also as a fun exercise to confuse students I generated annoying high pitch frequencies that only they could hear to assess their hearing loss due to age or damage due to loud music! It really got their attention if tied in to a speaker. As an amateur musician and engineer I highly recommend this app, just purchased the advertisement free version after 5 years of using the app.

Best Tuner I’ve used in over 8 years

Fantastic free to use tuner that should be absolutely embraced with hardly any ads interrupting your business. Every other free to use tuner I’ve ever used and including a paid premium app that I also had experience with, this tuner blows all of that out the water big time in my opinion, but maybe I’ve just not had good experiences with online mobile app tuners. I still prefer a real life tuner to any app by far but for something that costs nothing it does the job good enough.

My favorite tuner app!

Have used this app right before gigs in loud bar settings, somehow was always able to get things set just right. Very intuitive, very accurate! Stoked that I just found this again, the last tuner app I had was no comparison even though it’s currently the first tuner app listed on the App Store... stunk like fish lol
