Din: Decibel & Sound Meter

Din is a free, accurate decibel meter that answers one question the moment you open it: how loud is it?

The sound level meter starts reading instantly — a big dB number, a color that shifts from green (safe) through amber (caution) to red (danger), and a plain-language label like "normal conversation" or "very loud — hearing risk." No setup, no account, no tap required.

PRIVATE BY DESIGN
No account needed. Your microphone audio is analyzed on your phone and never uploaded anywhere.

Din uses your phone's microphone, so readings are estimates — tuned for everyday accuracy, but not a replacement for a certified sound level meter in legal or industrial settings.

How loud is it? Open Din and you'll know.
