Customer Reviews

Everything the app promises to be

Yes, this uses the built in iphone microphone. Derpa hurp duh. That means there is always an inherent limit of expected quality because of the hardware of the device being used. This app does not try to make any claims that this software is somehow more accurate than the limits of its platforms' hardware. That will never be possible, so I don't know why people are criticizing the app because of known device hardware limitations.

This app was exactly what I expected except of the added bonus of displaying SPL differences over a time domain! I would've been happy with just a numerical decibel reading, but this app includes a measurement-over-time feature as well as a pause/play button for examining a specific volume at a specific moment.

This app is great, it works great and the interface makes sense. If you're looking for scientific measurement of specific frequencies that your device hardware is unable to pick up with clarity, you should stop trying to use an iPhone/iPad (ya dingus) and invest in a decent microphone, preamp, and recording software with accurate loudness measurement plugins.

This app is perfect for the iPhone and its limited microphone. Anyone complaining about this is clearly drunk and should just go home already ūüėČ

Neat tool but take it with a grain of salt.

Obviously it's not going to be super accurate as it is just using the phone/iPad mic, but it is a near tool that can give you a rough estimate. I know one of the other reviewers had an issue with it not going above 100 or below 40 but if you read all the information the debs talk about this limitation. In short, it's fun, but don't base your thesis paper off its measurements.


This may lack accuracy for professional applications. But, it helps me determine when ear protection is needed. And since I began using this, I always carry earplugs for those times when chronic exposure to >90 db levels could cause damage to my hearing. Protecting one's hearing is important. This app helps me do that.
