Offline & private dB meter

What's New in Sound Level · Baro
1.0.6
August 13, 2026
What's new: • Noise limits by country: reference levels for Korea, Japan, Germany, France, the US and Saudi Arabia — with a plain explanation of when a phone reading can be set next to them, and when it can't. • Noise log: a private, on-device record of when it was loud, for how long, and how often. One tap while measuring saves the current stretch, and you can export it all as text. • Steadier measuring: if a call or another app takes the microphone, the meter no longer freezes silently — it tells you, and one tap starts it again. If anything looks off in your language, tell us from the "Built with you" card — we read every message.
