Din: Decibel & Sound Meter

Din is an 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.

MADE FOR REAL SITUATIONS
- Concerts and clubs: check the volume and know when to reach for earplugs
- Noisy neighbors and apartments: keep timestamped noise recordings as documentation
- Job sites and workshops: track exposure against workplace noise limits
- Baby rooms, offices, classrooms, studios: anywhere loudness matters

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

Din uses your iPhone'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.
