dB Meter - Sound Level Meter

No ads. No tracking. Ever.

dB Meter is the professional sound level meter that protects your hearing — not your data. While other noise apps monetize you with ads and trackers, everything here runs on-device. Your audio is analyzed live on-device and never uploaded; optional Pro recordings stay on your device, under your control.

MEASURE — REAL-TIME SOUND LEVEL METER
A beautiful analog gauge with a live needle, color-coded safety zones and real-world comparisons like "Library quiet" or "Rock concert". Min, average and max readings at a glance, with haptic feedback as levels change.

PROTECT — NIOSH-BASED NOISE DOSE
dB Meter tracks your daily noise dose against the NIOSH recommended exposure limit (85 dBA over 8 hours). One glance tells you whether today's exposure is in the safe zone — and an alert warns you before your ears pay the price.

UNDERSTAND — HISTORY & INSIGHTS
Every measurement is saved automatically. Charts reveal your daily averages, exposure timeline against the 85 dB line, loudest days and category distribution — so you learn where your noise actually comes from.

FREE VS PRO
Free users get the full real-time meter, frequency weighting basics and 7 days of history. Pro unlocks unlimited history, advanced charts, NIOSH dose tracking, calibration, dBA/dBC weighting and all themes — as a Monthly subscription, a Yearly subscription with a 7-day free trial, or a one-time Lifetime purchase.

WHY PRIVACY MATTERS
Most sound meter apps are ad-funded, which means your microphone data feeds someone's ad business. dB Meter collects nothing: App Privacy label "Data Not Collected". Audio never leaves your device. That is a promise, not a setting.

Built by an indie developer who cares about hearing health.
