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”. ### 5/5 — It’s good *2026-06-21, version 1.7.7* It’s actually pretty accurate and I like how it shows where u would be depending on the decimal meter ### 5/5 — Legal *2026-06-13* Legal ### 5/5 — Mega *2026-06-07, version 1.7.7* Erfüllt seinen Zweck ### 5/5 — Singlefathersthrive *2026-05-26, version 1.7.6* Gives the contrast between frequencies and side screen done well. ### 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. ## Frequently asked questions about Decibel Meter Ultra ### What does Decibel Meter Ultra do?
