### 5/5 — Best decibel in the store

*2026-08-04*

I love this tool.

### 5/5 — 方便

*2026-05-24*

好用，挺简洁、大方的，不错👍

### 2/5 — Not going horizontal

*2024-06-07*

I’m always using my iPad horizontally, this only for vertical users only and the average meter totally not accurate. The should let you know on the app before purchasing it. Waste of money

**Developer response:** Thank you so much for using my app and for your support!

I’m an independent developer in Canada, and I recently updated another app called TimeStamp Camera. It lets you add date, time, GPS location, address, and custom watermarks to photos and videos. It is free to download this week.

### 1/5 — Complete fraud for function

*2023-01-05, version 1.8*

App does NOT register correctly whatsoever. Completely quiet and still home, registers near 65-70..!? Two different compressors register the same even one is completely louder. 

This app is a complete failure.

### 1/5 — Don’t waste your money

*2022-05-25*

No noise in the room it registers 55db as a standard baseline read (I’m serious, it’s 3:43am here, everyone else is in bed, no tv, dead quiet house, stand-alone house, no noise from heater, fridge, street, neighbours etc & that is the read 🤦🏼‍♀️). Whispering it registers 95db. Speaking quietly it registers 110db. Talking normal range it is off the charts. God forbid anything above a normal conversation should occur! Save your money.

### 1/5 — Bug

*2022-05-24*

L’idée et bien mais il me dot que je suis constamment à 60db alors que je suis dans un endroit calme.

**Developer response:** Merci beaucoup d’utiliser mon application et pour votre soutien !

J’ai récemment mis à jour une autre application appelée TimeStamp Camera. Elle vous permet d’ajouter la date, l’heure, la position GPS, l’adresse et des filigranes personnalisés à vos photos et vidéos. Elle est disponible gratuitement au téléchargement cette semaine.

### 1/5 — Not accurate

*2017-07-17, version 1.6*

I purchased this app because of the ratings. I had dl'ed a free db that never matched what this one was saying. A buddy had an expensive decibel meter that I borrowed. This app wasn't even close and the free app was. I tried the adjustments to get it close and couldn't.
