I tried three different decibel apps before I gave up, they were never within 5dB of each other. My DeciSense gives one steady number every time, and that's finally something I can point to when I talk to my upstairs neighbor.

Phone mics aren't calibrated and can swing 5 to 10dB between devices. DeciSense holds ±1.5dB accuracy, so your reading is one you can actually trust.
DeciSense reads the full 30-130dBA range, from a quiet nursery to a loud workshop, past OSHA's 85dBA safety limit and beyond.

One button turns it on, one glance gives you a number. There's no menu to dig through or setting to get right before your reading counts.
Hit hold the second the noise peaks and the reading freezes on screen. Max/min tracking shows the worst of a session, not just a guess.

I tried three different decibel apps before I gave up, they were never within 5dB of each other. My DeciSense gives one steady number every time, and that's finally something I can point to when I talk to my upstairs neighbor.
I calibrate my home theater levels before every movie night now. Pointed my DeciSense at the sub during a bass test and finally saw real numbers instead of guessing if I was about to annoy the whole building.
I grabbed my DeciSense just to settle an argument about how loud our AC unit really is. Turned out our normal living room sits around 45dB, and the cicadas outside our window hit over 90. Genuinely surprised me.
