SPLnFFT Noise Meter

Very happy with performance of app! Using to balance sound levels between Music Keyboard and Simply Piano online lessons. But main objective is keeping listening volume at safe levels, preserving my hearing and preventing worsening tinnitus.

I am very careful with my hearing in loud environments. This App is excellent for reading loudness levels throughout my day. I sometimes work around an airport. I always protect my ears. It's nice to know what these loud situations could be doing to my hearing at the convenience of my smartphone. Update: I have had this App for over 8 years and still love it. The developer has maintained it all this time. So extremely happy for this. I used it recently when I was at a Wedding Reception. They seated us next to the speaker. I thought I was going to die. It read 96-97 db’s. I showed the people at my table how loud it was. They were surprised. And also showed them this can cause hearing damage if we are to sit here the whole night. Anyway, got out of that situation before the exposure limit. So useful. Thanks again! Michael

Wouldnt download. I purchased app for $5 usd like a dummy. There’s no in app support. The data you can export is extremely limited csv. Other apps allow you to video record w/audio db levels. Even though I paid for the professional version of this app it will not unlock the feature. It’s a scam. Cant even contact developer in app.

The app is well designed and actually looks like a real sound level meter. The app works very well and is also accurate. I have tried all of the sound level meters for iOS, and this one is far superior. Congratulations to the developers. Great work!

I use this app several times a year and have used it for many years. It is a fantastic reliable and useful app. I highly recommend it. It’s very helpful when measuring speakers, general levels of noise if I’m in an audience, and I even use it with over the ear headphones (I just get the mic-end of the phone as close I can where my ears would reside within the earpiece to get a general idea so I protect my ears). If you don’t have a dedicated spl meter (or don’t carry one around with you) I recommend you get this. You won’t be disappointed. 🙂

Seriously! This app is awesome.

I keep it on my first page. I’ve had it several years. I have not noticed any bugs.

I’ve used this app for several years, it’s extremely accurate. I use it mainly for live music inside a club venue. This app stays reliable and steady along with upgrades of phones. I’ve found zero inconsistencies. It does help me show guitar players that their stage amp is louder than the PA.

This is a must-have for anyone who cares about sound, audiophiles, sound engineers and even concert goers. Use this to adjust tone controls on your car stereo or see how loud that club really is. With this app, I know for sure when to insert my earplugs. I am not associated with the developers.

Incredible feature set. Very customizable. Super reliable. Frequently updated. What more could you want?
