Very good app!

I work as a Maintenance Engineer for a hospital. We have a very expensive Db meter that is hard for a novice to use (very complicated) this gets almost exactly the same readings and very easy to use. I love the email function. I would give it 5 stars if you add more instructions for us users that don't have the knowledge or experience to understand all the settings. Thank you for creating the app! I will be buying the Pro version (to rid myself of the adds) are the differences between this version and Pro just the Adds?
I'm amazed that this app was even close to our our real, expensive Db meter. It made a believer out of me.

The perfect app for curiosity!

I got this app because the other DB app became bombarded with full screen ads.

I am happy that there is a free version without any time limits on how long you can run the app, and the bottom banner ads are fine with me, it is the full screen ads that I dislike.

However due to there only being one full screen ad on startup followed by non stop banner ads, I am very pleased with this.

I can leave the app running while it cycles through the banner ads, the developer gets money, and I don’t have to deal with annoying pop-ups! It is wonderful!

The translations are a bit confusing , but there is enough there to understand what they are trying to say.

The interface and data is displayed wonderfully! Not too simple, but not overwhelmingly complicated, and if you need help, there is a button that explains what everything means.

In short it is a wonderful app that successfully has gotten its own spot on my home screen, and it won’t be going anywhere anytime soon.

Keep up the good work!

Awesome app

More settings then I know what to do with. I have tried 25 spl meters and they all want to charge for any weighting other the A. No Apple tax!!!
