Decibel Meter: Sound dB

As a HVAC tech, I use this app for quick, preliminary sound checks on units before and after service. The ability to save a "before" and "after" reading right on my phone is incredibly handy for customer reports.

I’ve tried several sound meter apps, but this one stands out for its clean interface and reliable readings. The analog-style gauge feels satisfying to watch, and the history feature lets you track noise over time.

I especially appreciate the current noise reference feature, it helps you understand what different decibel levels mean in real life. You can also set alerts to avoid being exposed to dangerous noise levels.
