### 1/5 — Very wrong

*2025-10-01*

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.”

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