How to cancel Decibel Meter Ultra subscription ⁉️

User reviews

Not functional and erroneous charge

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

Only a 8 days demo, mentioned nowhere on the app page…

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

Response from developer

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.

Free Trial Tries to Make a Purchse

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”.

Response from developer

Thanks for the feedback, and sorry for the confusion. A 7-day free trial is still started through Apple’s App Store subscription system, so if in-app purchases or subscriptions are disabled on the device, Apple may block the trial and show a “purchases aren’t allowed” message. This does not mean the app is trying to charge immediately before the trial. The trial, price, renewal terms, and confirmation are all handled by Apple before any subscription can begin. The app also includes a free version, which can be accessed by closing the payment offer screen without starting a trial or subscription. We’ll continue working to make this distinction clearer.

It’s good

It’s actually pretty accurate and I like how it shows where u would be depending on the decimal meter
