Essential FFT

Not so much as a tuner, (which is fine), but for the excellent FFT! This is the best FFT for general use on iOS. I teach acoustics and I use this FFT for live demonstrations of the analysis of sound. The FFT graph is smooth and easy to use. “Seeing” noise, or the harmonic series of instruments is great regardless if you’re using an iPhone or an iPad Pro. Due to the high resolution of the iPad Pro display, screen captures as videos are high resolution too.

If you’re looking for a simple FFT that looks great, download the free version and give it a shot.

Well worth the price

Accurate easy-to-read tuning even when there's background noise. I spent a long time looking for the perfect tuner and am happy with this one.

Request: Please make the app remember the view that was chosen the last time the app was used. Or provide an option to select a default view.

Helpful but needs some improvement

I really like this program overall. The difficulty I experience is that there seems to be a lag time between the time I tune and the time it registers on the screen. This makes it difficult to know when I’ve actually tuned it properly and frequently I have to retune because the pitch is now too sharp. Also it could “listen” to the pitch a little longer.
