User reviews

Very wrong

Reads 20 dB lower than it should, even with calibration maxed out, on both ipad and iphone, and compared to both apple watch and another db app. It also claims a roaring air conditioner is “very quiet.”

Response from developer

Hi, you can calibrate it from the settings. By default, we’ve already calibrated it using a sound meter. Thanks.
