• Graphical Representation: A historical graph tracks decibel levels over time, offering a detailed view of sound fluctuations.

Whether you're monitoring a workplace for occupational noise compliance, or conducting an acoustic tuning of musical instruments, this app provides the precision and flexibility needed for all your sound measurement needs.

### 1/5 — Automatically charges your card

*2024-07-07*

It’s only free to download. To actually use it, you have to buy a subscription. Even the 3 day “free” trial comes with you automatically subscribing to your card being charged weekly. I haven’t been able to find where to cancel the subscription. It’s hidden too deep in some settings so I’ve not been able to find it.

### 1/5 — Not good

*2024-06-23*

Drop the price to free from $2.99 but require a monthly subscription to use.  Cannot even begin to use without a subscription.  Avoid this app!!!

**Developer response:** Thank you. We constantly update the application to provide the best service for you.

### 1/5 — Free this week, but cannot test it out

*2024-06-21*

Having this as a free app, sounds great! But upon first launch, you cannot test it out without buying a subscription. How can I decide if I want it?

**Developer response:** We have already added a 7-day trial for you to try for free. There is no fee charged. You can cancel at any time.
