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 spy on you with ads and trackers, we believe your sound data is nobody's business but yours. Everything runs on-device. Nothing leaves your iPhone.

- REAL-TIME SOUND LEVEL METER
Measure ambient sound instantly with a beautiful analog gauge. Color-coded safety zones — green (safe), yellow (moderate), orange (loud), red (dangerous) — tell you at a glance whether your environment is safe. Real-world comparisons like "Library quiet" or "Rock concert" make the numbers meaningful.

- FREQUENCY WEIGHTING (PRO)
Switch between dBA, dBC, and dBZ — the same filters used by occupational safety inspectors and sound engineers. dBA mimics human hearing. dBC captures low-frequency energy. dBZ provides flat unweighted response.

- NOISE DOSE TRACKING
Monitor daily noise exposure using the NIOSH formula. The app tracks how much loud sound your ears have absorbed, alerts you before you hit unsafe levels, and treats your ears like a step counter treats your feet.

- CALIBRATION (PRO)
Fine-tune readings against a reference meter for professional-grade accuracy. One-time setup, saved forever.

- RECORDING & CSV EXPORT (PRO)
Save audio clips of your measurements. Export your entire history to CSV for analysis in Numbers, Excel, or any spreadsheet. Perfect for workplace documentation, science projects, or noise complaints.

- MEASUREMENT HISTORY
Every reading saved locally with SwiftData. Timestamp, location context, peak level, weighting mode — all stored on your device. Free: 7 days. Pro: unlimited.

- INSIGHTS & ANALYTICS (PRO)
Beautiful charts reveal your noise exposure trends. Weekly and monthly summaries surface your loudest environments, average exposure, and hearing safety score.

- DAILY HEARING HEALTH TIPS
14 NIOSH-aligned tips teach you how to protect your hearing — one lesson per day. Science-backed, jargon-free, actually useful.

- STREAKS & ACHIEVEMENTS
Build a habit of checking your environment. Earn milestones, protect your streak with a weekly freeze, and celebrate progress with a full achievement gallery.

- SMART NOTIFICATIONS
Exposure warnings when noise crosses safe thresholds. Streak reminders before your day ends. All opt-in, all respectful — never spam.

- HOME SCREEN WIDGET
Add the dB Meter widget to your Home Screen for a quick shortcut to your next measurement.

- SIRI SHORTCUTS
Say "Measure noise with dB Meter" or "Open history in dB Meter" — Siri handles the rest.

5 themes, 2 free and 3 Pro. Dark mode by default, with full accessibility support: VoiceOver, Dynamic Type, Bold Text, Reduce Motion. Works on both iPhone and iPad.
