The honest sound level meter that tracks your real noise exposure. Turn your iPhone into a real-time dB(A)/dB(C) sound level meter — live waveform, peak, average, and Leq — then watch it roll into your daily NIOSH/OSHA noise dose. Fair pricing, no weekly traps. ▸ MEASURE SOUND INSTANTLY Open the app and start reading in real time — no setup, no sign-up. • Live dB(A) gauge + scrolling waveform — see the room react as it happens • Min, average, max, peak, and Leq — the numbers a real meter shows • "How loud is this?" scale — from rustling leaves to a jet engine • Clear Start/Stop and named sessions — measure, save, and revisit ▸ KNOW YOUR NOISE EXPOSURE Most apps stop at a single number. Decibel tracks how that noise adds up. • Daily noise-dose ring — NIOSH (85 dBA) and OSHA (90 dBA) standards • Loud-event alerts — a heads-up when sustained sound crosses 85 dBA • Exposure timeline + charts — see your week, not just this second • TWA and total exposure time — the metrics that matter for your hearing ▸ ACCURATE & TRUSTWORTHY Built to read honestly — and to tell you when it can't. • Measurement-mode capture — disables auto-gain for stable readings • Mic calibration offset — fine-tune against a reference meter • A, C, and Z weighting — dBA for hearing, dBC for bass and peaks • CSV & PDF reports — clean exports for complaints, work, or your records ▸ FAIR, HONEST PRICING The category's loudest complaint is price. We fixed that. • About half the price of the leading sound meter apps • No weekly traps, no à-la-carte unlock packs • A genuinely useful free tier — the live dBA meter is always free ▸ FREE VS PREMIUM FREE: • Live dB(A) meter with waveform, peak, average, and Leq • Today's noise dose • Your last 3 saved sessions PREMIUM unlocks: • Unlimited measurement history • dBA, dBC, and dBZ weighting + mic calibration offset • Full exposure timeline with charts • CSV & PDF noise reports • Zero ads ▸ PREMIUM SUBSCRIPTION Decibel Premium is available with the following subscription options: Monthly: $4.99/month Annual: $24.99/year — includes a 7-day free trial Payment will be charged to your Apple ID account at confirmation of purchase.
