1. 5/5Essential 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.

2. 5/5Best Tuner in the Biz

   If one is in need of a tuning mechanism, I can think of no application I could recommend more than this wondrous specimen of human technological musical tuning-based ingenuity. Truly, I am in awe of its majestic splendor. It is magnificent. I'm actually not kidding this is a great tuner.

3. 4/5Helpful 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.

4. 5/5Tuning

   I use this app to tune my viola and it works great. There are many different visual options for when you tune. I compared my viola to my piano (which is tuned) and it was on POINT!!!!

1. 5/5

   Works on Google Watch 4 accurately with high frame rate and shows the spectrum. Would be nice if the dev made it as a "tile" for quick access my watch.

   Best tuning app I've ever used, it's criminal that it's not more popular

3. 4/5

   I like everything about it except that it won't stay on my instrument. I only use it to tune a violin but every time I open the app it's back on guitar. Please make it possible to set a default instrument, or just leave it on whatever I picked last. Otherwise it's great!

5. 5/5

   best tuner I've used. you can play a crisp sine wave at ANY frequency and tune by ear, or use your microphone like a normal tuner. I've used this tuner for years and will never switch to another
