Noise Killer

worse app. to big cant see it on phone. Cant change size of app. The no help. cant uninstall it. completely driving me nuts. CANT STAND THIS APP. now its interfering with my phone sounds. SUCKS

Hahaha, there is 0 difference with and without app, zero! My understanding is that it should read the sounds around and feed my headphones with those sounds reduced by phase difference. It appears that nothing os being fed to headphones. Pathetic.

Does not kill your surrounding noise. The app merely points out that noise has been detected

Check out this app it'll take less space in your phone and does the same thing, noise.decibel.measurement

Just a noise measuring tool

Doesn't let me select alert types

Ad covers app. Can't use it

fun app but it wont reduce noise lol

Just a noice meter.... misadvertising ...

Now as described, this is just an opinion based on use for short time. The thing I hated instantly is that ads pop up just where the the minus button is. Means I can increase the alert noise level but not decrease it while the ad is up. I need more testing on how good it is at noise cancelling. I will update when I have used it for a fair amount of time.

I got rid of the ads by putting my phone on airplane mode (my 13 year old's idea) but I still can't access the options to have the app make a noise or shhh when it gets too loud. Everything gets cut off on my screen.

Please fix resize and make the settings easier to find. Works great on our Galaxy S3. Also, could you remember the previous level setting instead of defaulting to 60db?

Useless, impractical, unacceptable especially I libraries!

Pathetic app, ad cover imp settings

Cannot see choices for sound alerts, too big to fit my screen

Not so good don't vibrate

I'm assuming it's too big for the screen since all it does is tell me the decibel level and show me adds

I love this app on my tablet but on my phone the screen is so big that I can't adjust the alarm settings. Please fix this for a 5 star rating. 8/24/16 Please fix!!!!!!!!!!

If I could change the notification sound from vibration it would be much better.

Not working well on nexus 6p

Ad covers app. Can't use it

Like it....

Please fix this

To confusing

I was looking for active noise cancellation apps and bumped into this. Although it doesn't solve my purpose,I like the concept and can imagine it being a useful app in places where you need to keep reminding people to be quiet.

Now as described, this is just an opinion based on use for short time. The thing I hated instantly is that ads pop up just where the the minus button is. Means I can increase the alert noise level but not decrease it while the ad is up. I need more testing on how good it is at noise cancelling. I will update when I have used it for a fair amount of time.

It does what it says, but the adds block all the options to change the vibrate to any noise... Bummer

I like this for helping my class self monitor their noise level. Can't see too much at bottom because of the ads.

It did not even lessen the existing sounds.

Might be they should change the name of the app, but this could be useful in places library or bedroom, when your baby is asleep. Will help you keep your voice in check.

It works for me. It's fun, and got a sound measuring decibel meter too. When someone talks loudly, the device warns "QUIET PLEASE" "SHHHH...". I keep the phone connected to my loudspeaker! LoL. I can now forcibly make my wife speak low thru the phone automatically when she raises her voice. And, she just smiles! LoL. Have it! :-)

Pathetic. Would give it less than 1 if possible

Can't do anything with the buttons covered

I like this app but the ads cover the settings. That needs to be fixed.

Good app... But, it will be even more useful, if it can also work as a background task.

The ads sit over the settings making them impossible access and manage the app.

It is good , it appears that there is further scope of improvement.

I used to use this app all the time. Now I can't access the speaking options on bottom and ads cover the volume buttons. Hope it works again soon??!

Rubbish

Not that good because it doesn't allowe to record a sound to use it
