Contact Decibel dB sound level meter Support

I paid for Spectrum Pro, Dosimeter Pro, and dB Meter Pro. I just noticed that now I no longer have Spectrum Pro because it now requires an $8 monthly subscription. I still have Dosimeter Pro and dB Meter Pro (until they also require a subscription). I was confused about which one would export data to Apple Health. However, I happily paid for them all because all I wanted Apple Health tracking. But now even that has become unavailable. I turn on export to Apple Health. It shows it's on until I leave the settings page. I go back to find it's off every time. How can a developer, in good conscience, take away features they once offered for a one time fee? All because they want to hop on the subscription bandwagon like all other apps. I want the features I bought. I understand developers need to get paid, but customers who paid before you switch to subscriptions should get to keep all the features offered at their time of purchase.

The basic dB meter itself seems to work okay but isn’t going to tell you much more than your own ears can likely figure out. I was hoping to be able to detect very high pitched sounds but that doesn’t seem to happen. The worst part though is the pop-ups to purchase the several different pro versions. If you press the home button to back out of it with a phone that confirms purchases with your finger print, you end up paying for whatever “pro” version pop-up they are showing... and there are seemingly endless “pro” options. This feels very deliberate and appears to be a scam. I ended up with a $10 purchase I had no intention of making and still get prompted non-stop for more purchases! Avoid this app!!!!

Be very careful. This app tries to sell you upgrades & subscriptions. The purchase window pops up as fast as you close it. While contemplating how to get out of this loop my thumb touched the home button & I was charged $9.99. Update: first of all I was not upgraded to the Pro version. I have no idea what I was charged for. I went to PayPal & found a recurring charge that I immediately canceled. Secondly, I did not push the home button to close the purchase window. I pushed cancel, but a new purchase window popped up immediately. It was stuck in a loop. There was no way out. If you read the reviews you will find a large number of inadvertent purchases. Obviously this app is designed to take advantage of bugs built into it.
