### 4/5 — Utile

*2026-04-22*

Permet de mesurer les niveaux sonores par fréquences et déterminer les niveaux à ne pas dépasser dans la durée Merci aux développeurs ! De France Thierry

### 2/5 — Lacks finer resolution

*2026-03-31, version 1.7.1*

1khz tone reads as 1.19 , not good

### 4/5 — Belle appli

*2025-12-24*

Malheureusement je n’ai pas de vrai sonomètre pour valider les mesures. Très surpris de voir que j’ai aussi peu d’aigus sur ma Hi-fi.

### 4/5 — Love it !!!

*2025-12-11, version 1.6.11*

Only thing is it’s too expensive.  It’s worth $10 to this 72 year old retired person.  I will keep looking.

### 5/5 — My favorite!

*2025-11-10, version 1.6.11*

Works well, easy to use and read. Excellent service!

### 5/5 — Great meter!!! So useful!!!

*2025-11-06, version 1.6.11*

Works perfectly !!! WOW!!!!!

### 3/5 — Pas précis, voir trop

*2025-11-04*

L’interface de l’application est très fluide et parfaite. 
Par contre au niveau mesure, j’ai environ 20db de plus voir 30 par rapport à mon appareil professionnel validé par l’état français.

### 1/5 — Rip off

*2025-10-04, version 1.6.11*

They will charge your Apple account

### 4/5 — Drôle

*2025-09-27*

Drole

### 1/5 — Geht es noch?

*2025-09-25*

Entspricht nicht den Realität

**Developer response:** Hallo ProNutzer15, vielen Dank für Ihr Feedback. Es tut uns leid zu hören, dass Decibel Meter Ultra in Ihrem Fall nicht die erwarteten Ergebnisse geliefert hat. Die Messgenauigkeit kann je nach Gerät und Umgebungsbedingungen variieren, und Ihre Rückmeldung hilft uns sehr dabei, die App weiter zu verbessern.

Wenn Sie uns nähere Informationen zu Ihrer Situation geben könnten, schauen wir uns das gerne genauer an. Sie können uns jederzeit über den Support-Link in der App oder über unsere App-Store-Seite kontaktieren.

Beste Grüße,

### 1/5 — Not functional and erroneous charge

*2026-07-25, version 1.7.8*

This meter does not accurately record sound levels. I placed it near a shared wall while experiencing loud hammers and high pitched mechanical wining. It showed nothing. Further although I toggled the paid version off before downloading I’ve still been charged 39.99 for this worthless app

### 1/5 — Only a 8 days demo, mentioned nowhere on the app page…

*2026-07-24*

Apple, plz enforce any devs to inform users if they install a time limited demo or a free product………..Thank you !)

**Developer response:** Thanks for the feedback. We agree that it should be easy to understand whether an app offers subscriptions or other in-app purchases before downloading, and we’d welcome any improvements Apple makes to increase their visibility.

For future reference, the App Store product page indicates when an app includes in-app purchases directly below the Get button. You can also scroll to the Information section, open “In-App Purchases,” and view the available subscription products and prices before installing.

Also, you might be interested to know that the app is not limited to a short demo: it also includes a free plan, which can be accessed by closing the payment offer screen without starting a trial or subscription. We’ll continue working to make that option clearer within the app.

### 1/5 — Free Trial Tries to Make a Purchse

*2026-06-25, version 1.7.8*

This app starts with a page saying you can try a “7-day free trial” of this app, and has a “Try for Free” button below this.  If you have In-App Purchases turned off on your device, tapping the “Try for Free” button gives an error message that purchases aren’t allowed, and it won’t let you continue.  It shouldn’t be trying to make a purchase for a “Free Trial”.

### 1/5 — 課金させられた…？

*2026-05-18*

アプリすぐ消したけど課金の方消すの忘れてて自動的にお金取られてました。請求できるようにしてほしいです。

**Developer response:** ご不便とご心配をおかけして申し訳ありません。アプリを削除しても、App Storeのサブスクリプションは自動的には解約されないため、Apple IDのサブスクリプション設定から解約手続きを行っていただく必要があります。

請求の確認や返金をご希望の場合は、AppleがApp Store上の請求を直接管理しているため、reportaproblem.apple.com にアクセスして返金をリクエストしてください。

予期しない請求に感じられたこと、申し訳なく思います。今後も、サブスクリプションや解約方法がより分かりやすく伝わるよう改善してまいります。

### 1/5 — Ugh

*2026-04-26, version 1.7.1*

I collected data for an hour. I even started the free trial to make sure I’d have access to the data, hoping that would be helpful. I switched to the $1.99 a week so I wouldn’t get a $50 randomly. Data lost! So disappointing.

### 1/5 — You charged me before the free trial ended! I have signed up today and recieved an invoice just now!

*2026-04-18, version 1.7.1*

This app has stolen my money before I could even try the app properly! 
I want my money back immediately and I won’t be renewing.

### 1/5 — £7.99 a week

*2026-03-22, version 1.7*

App works ok but the price is madness

### 1/5 — Paid slop

*2026-01-07, version 1.6.11*

Yet another pay to view

### 1/5 — Nope

*2025-11-29, version 1.6.11*

REQUIRES installing pro version; you either buy it on the spot or you start your “free trial” but either way you can’t use the meter unless you install pro. Hard no.

### 1/5 — Beaware of scam

*2025-10-16, version 1.6.11*

Paid them 8.99 + taxe a month i didnt even know
