Decibel Ultra App Reviews

The best you can get for free! Ive tried a few others.

You cant really set it to zero once youve changed it

Great except the decibel offset bar is to sensitive it would be nice I u added+ and - controls

I was at a concert and wanted to measure how many decibels the obnoxious band had their guitar up to and it said 100, however when I am sitting here talking at a tolerable volume it jumps up to 100. Never surpassing it. Im no sound expert but that doesnt seem right.

Try using a real decimeter. It works the same as this app only can cost up to $100. The closer you are to the source the louder it will be. So if a band from 50 yards reads 100db. Dont be surprised when your talking voice is the same at 2 inches. Do a little research before you post negative comments. I am a sound engineer. This app works nearly as well as many decimeters do.

The new version is supposed to be calibrated for the iPhone 4S, yet when I exhale about a foot from the mic on my 4S, it registers at 93 dB which is supposed to be louder than a car horn. I have a real meter and the values this app reports dont match at all. Likely its not weighted correctly.

Very helpful to find loud places and a quick response to fix noise problems

Ive downloaded a few db apps and found this to be the best!

very nize :)

I Dont know yet if it is precise but I like the fact that you can calibrate it , and it has another functions.

I have been using this app to compare interior noise in cars. Works great!!

App seems nice but I get blank emails after recording a sample. Really would like this feature to work as its very important to me and what made me pick this app over others.

Also cannot email results, and get a blank email!!

Looks like the person who wrote this app doesnt care that much about it. Its near the end of February 2013, and you still get a blank email after recording a sample. Thats the main reason I picked this app. Without it its fairly useless to me. Doesnt seem as if the developer cares, since people have been complaining about it since at least November 2012.

You get what you pay for? Lots of potential, but this app is relatively confusing, with a bad UI, and sadly, the "record a sample" feature (that is intended to include the data log into an e-mail) appears to be broken, at least in recent versions of iOS. That said, if youre looking for a free sound metering app, this one has some solid features, for free. Just takes some patience to figure out its quirks.

Really I dont know much about this stuff but I did see a web page talking about this dudes 18 in sub that hits a "whooping" 134 dB. Well Im currently riding in a car with the volume on low and no substantially great speakers and according to the app Im hitting 70-85 dB. Something just doesnt seem correct to me...

I am a Medical Doctor and App Developer who is concerned with noise pollution and hearing loss. I use it to quantify the level of noise in my environment.

Prior to the iOS7 update the app was working fine. Seems broken now.

The app does not seem to work with iOS 7. Very disappointing.

It used to be a great app, but since iOS7, its not working at all. Please fix it!
