A Google user: “Very useful! Though I haven't checked the reading accuracy (though it states very clearly that it's not a perfect dB reader). I would like to measure sound levels with the screen off, and without it ruining the lowest recorded dB level. I would also love to be able to make and export basic logs of results. ...Thanks for a great app!” – 4/5 in Play Store

A Google user: “SO FAR I like this sound meter, however I have to run it next to my Amprobe SM-20(ANALOG) and my Fluke-945 (DIGITAL) to check its authenticity as relevant to reliability! In regards to ADS in the app, any ad is disruptive but these are really not in anyones way, but yes there are ads! What I REALLY DON'T LIKE in this tool is icons that lead me into other apps (compass, vibration meter) that I REALLY DON'T want added in my sound meter app!! BUT, I do like having this sound meter tool in my phone, that way as a professional audio engineer and drummer I always have a sound meter with me!!!😁” – 4/5 in Play Store

A Google user: “The app gives consistent decibel values when using it on my Pixel 2 XL, so the basics are solid. It's not my favorite, but I have Play Pass so I take advantage of how simple it is. 4 Stars: Considering it's not completely free, it would be nice to have some more features like logging or more control over the view. There are other completely free apps that give more detailed real-time information on the sound around you. It's consistent, so the dev certainly has an accurate start to build on.” – 4/5 in Play Store

Uckerfay: “not very accurate. it regularly posts levels around 20 decibels higher than actual. it is also not the easiest thing to read st a glance. I had much better success with the Sound meter App from "Creative Gigs". it posted much closer to the actual sound level, is easy to read, and actually tells you what the sound is coming from with decent accuracy. if the devs worked on these issues, it would be a much better app.” – 2/5 in Play Store

Make sure phone is in the same orientation and distance from source during your comparative analysis. Not sure about absolute accuracy as a sound meter but you can adjust your phone microphone in the app to match a calibrated meter reading. This is not important to me for my purposes and readings seem to fall within the descriptive ranges.” – 5/5 in Play Store

A Google user: “Easy to use, straight-forward, self-explanitory, to the point, not weighed down with ads even though they're utilized, clean with no unnecessary filler. I give it the highest rating on my own personal scale, which is 99, I only go to 99 when ranking apps which use ads, otherwise I rank to 100.

Comments and Reviews from users:

A Google user: “It's a very handy app, however I think itd be more effective used indoors only. It denotes basic street noise while recording, but if theres a very loud noise unusual for the environment, it will still change the high end decibel level to the one for that isolated incident. Perhaps there's more to it than I was able to get to in my rush & if I go back & Im able to account for the sound that I'm specifically trying to capture (a voice yelling thru a bullhorn e.g.), then I will up my rating to 4 stars. I can't give it 5 stars since it won't export or share the data unless you pay to upgrade it.” – 3/5 in Play Store

Drew Ryan: “It's pretty spot on. Out of the box it was about 3 or 4 decibels off. The running graph is very nice if you have to stop to look at the result of your test. The ability to save your tests is very handy and it's ready to go immediately after installation as it requires little initial setup. Its a good application; I'll definitely continue to use it.” – 4/5 in Play Store

Kicks, snares, claps, and hi hats as well, if you know what to look for. Very useful in eyeballing certain melodies of songs if you can't pick which notes are played in your head. Useful and fun. Also note: the quality of the visualization is directly proportional to the microphone quality, distance from sound, and the volume of sound.” – 5/5 in Play Store

A Google user: “Seems to work pretty well and is very easy to operate. I will use it in an upcoming test to see how accurate and responsive it is. I don't see a way to have it record the audio track, that would be helpful. It would also be nice to be able to get the data from the spectrum and / or time history out to a text file. The only other thing that would be nice is to play the file back for review and to allow the speaker to also play back the audio and spectrum. I wished the test audio played through the speaker, as well. Great tool!” – 5/5 in Play Store

A Google user: “Accurate enough for what I needed it. I just didn't want to be a nuisance to my neighbor. I know that my TV volume does not really go through to his apartment, so I used the app to measure the dbs from the TV and then turned my guitar amp to the equal level;even though the kind of signal is different the level was approximate enough for her to give me feedback and say it doesn't really make much of a difference.” – 5/5 in Play Store

A Google user: “It picks up the low frequencies i am hearing. It says its a clock ticking, but there is no clock in the house. It is picking up a deep low sound hitting the walls of the house. No one else can hear it but me. It is very loud to me. This app lets me show people the vibration i hear and feel. Awesome app. Wish it could correctly identify the sound though” – 5/5 in Play Store

Janvin Lowe: “A great sound recording app that uses the multiple mics on your phone which help in picking up (and actually amplifying) low-frequency noises (not the best but still very decent) and it's got diff modes (ie. one that records just audio and a video mode which records a video and has the audio graph as an overlay with the dB reading up top as well).” – 5/5 in Play Store

Norbertas Kremeris: “Out of ~10 sound meter apps i've tried on the appstore, this is likely the best - straightforward to use, no nonsense, and most importantly, saves and lets me export the audio files.

Comments and Reviews from users:

Mark Manning: “This is a nice app however it really needs to have a larger dial that's first thing the dial needs to be graded more so that you can see the little tick marks between each one of the numbers, and the recorded data needs a date time stamp on it so you know when the data was accrued. Otherwise this is the first app I've seen that actually records the information.” – 3/5 in Play Store

donnie spiller: “Easy-to-use, lightweight app. No ads! App appears to be as accurate as can be expected using Android device. Uses phone mic to detect signals. Phone mics are not as sensitive as professional SPL meters/dosimeters. However, this app is excellent in its own right for checking common everyday sound levels. Also, It would be nice if the app had a reference listing indicating what devices are equivalent to producing such decibels detected. I fully recommend this app.” – 5/5 in Play Store
