Sound Meter

My Experience with Sound Meter

Honestly, the biggest surprise was how accurate it felt for a free phone app. Last month, my upstairs neighbor got a new sound system, and the bass on a Tuesday night was shaking my ceiling fan. My roommate said it wasn’t that bad, but I was sure it was insane. I grabbed my Pixel 7, opened Sound Meter, and just held it up. Seeing that number jump to 78 decibels—way louder than a normal conversation—was the “I told you so” moment I needed. It turned a feeling into a fact. Since then, I’ve used it for dumb stuff too, like proving my blender is louder than my vacuum, or checking if the library is actually quiet (it’s not, it’s like 45 dB with all the typing). It just works when you need it to.

Features Worth Noting

The main screen is perfect. Big number, a button to pause, a button to record. That’s it. I’m not trying to be a sound engineer, I just want to know how loud something is right now. The recording feature is the hidden gem, though. I let it run for an hour during one of my neighbor’s movie nights and saved the session. The graph it showed me had these huge spikes during the action scenes. It was perfect to have that proof, not just a complaint about “noise.” I also messed with the alert feature. I set it to buzz my phone if things got above 85 dB, and it actually went off when a fire truck passed me on the street. It’s a clever little touch that makes it feel smarter than a basic meter.

What Needs Work

For the simple stuff, it’s great. But if you poke around in the settings menu, things get confusing fast. There are options for “A-weighting” and “C-weighting” and I have zero clue what that means. I tapped it, the numbers changed, and I had no idea if it was more or less correct. I had to Google it, and even then it was technical jargon. The app doesn’t explain it at all. Also, while the ads at the bottom aren’t videos (thank goodness), sometimes they’re for really loud, flashy mobile games, which feels ironic for an app about measuring sound. A few tooltips or a simple “this setting is for…” note would go a long way.

Pricing

It’s free. Completely free. For an app I’ve used for months, that’s pretty wild. There’s no “pro” version nagging me, and all the core features I actually use—the live meter, the recording, the alerts—are unlocked. The banner ad is a totally fair trade-off. I’ve used other meter apps that pop up full-screen ads every time you take a reading, which makes them useless. This one lets you just do your thing. If you need lab-grade precision, you’d buy a real device. For settling debates and satisfying curiosity, this free app is more than enough.

Developer Notes

I’ve never had to contact support because nothing’s broken for me. But looking at the Play Store page, the developer, rootApps, seems active. They push updates every few months, usually just saying “bug fixes and performance improvements.” My Pixel 7 got a big Android update recently, and the Sound Meter app kept working fine, so they’re clearly keeping it compatible. The app itself feels solid and not bloated with new features every update, which I like. It does one job and doesn’t get in its own way. The reviews are mostly positive, with people complaining about the same technical settings I found confusing, so maybe they’ll simplify that one day.

Security & Privacy

This was a concern for me at first—an app that’s always listening with my microphone? The permissions are straightforward: it needs microphone access, obviously. But it doesn’t ask for anything weird like my contacts or location. I checked its Data Safety section on the Play Store, and it says it doesn’t collect or share any user data. The app works completely offline, which is a huge plus. Nothing I record is being sent to some server. It’s all just staying on my phone. That gave me the confidence to use it freely, even to record the noise levels in my own apartment. It feels private, which is how it should be.
