1/5Don’t buy here’s why
Don’t purchase this app. The meters are inconsistent. You’ll get a measurement then it changes completely. Not stable.

1/5Too inconsistent
The meter is too inconsistent compared to other meters. Wouldn’t recommend paying for this.

5/5Quick & Easy
Earlier this week I and some friends went to hear the Yonder Mountain String Band play at the Ryman Auditorium. While I very much enjoy bluegrass music, the sound was painfully loud. The younger crowd didn't seem to mind the volume, but to a older person like myself, it was very uncomfortable. Luckily, someone had an extra pair of ear plugs and I was able to enjoy the rest of the show in comfort. But….. I still wondered how loud was the music? I pulled out my iPhone 4s and went to the AppStore. I bought "SPL Meter" based entirely on looks. It looked like an spl meter should look. Once downloaded, I found the app easy to use with intuitive controls. Where we were sitting in the center of the balcony, the levels averaged between 97 and 101 db. Pretty loud! The next day I cranked up my stereo at home to the same levels as the night before so I could experience the volume in familiar surroundings. The discomfort was the same! In summary, SPL meter suits my purposes very well because it's handy if I need it. I have no idea how it compares to professional meters.
