AskAudio's in-depth review of UltraTuner for iPhone, iPad and Apple Watch is the clearest confirmation yet of the power and flexibility of this remarkable app: "Quite simply, UltraTuner is the best iOS tuner you can buy. It’s extremely fast, remarkably accurate, highly configurable for noisy situations, and can make you feel extremely confident and stress free when tuning. At less than $5 it’s a no brainer. Buy this app!"

AskAudio have given an in-depth review to UltraTuner and are clearly very impressed with what they found.

Here are some of their key comments:

"After downloading the app and using it for the week, it’s graduated to the front page of apps on my phone, an honor only reserved for a select few."

"If you’re used to clip-on tuners or free/ad supported tuning apps I’ll warn you—once you use UltraTuner you’ll never go back."

"UltraTuner is fast, responsive, and accurate."

"The input can be calibrated for maximum effectiveness, and when paired up with an interface that bypasses the internal mic (like the iRig) you can count on a clean signal."

"In ‘studio’ mode, you have a strobe style tuner that is accurate to within .01 cents, and its reaction time feels absolutely instant."

In their final conclusion, they make no bones about their high opinion of UltraTuner:

"Quite simply, UltraTuner is the best iOS tuner you can buy. It’s extremely fast, remarkably accurate, highly configurable for noisy situations, and can make you feel extremely confident and stress free when tuning. At less than $5 it’s a no brainer. Buy this app."

Pros: Fast, responsive, simple interface, highly accurate
Cons: None, Really, none. It's great
