## Description

Accurate dBA readings, free and on by default. Calibrated for your iPhone, typically within ±3 dB of a professional meter. No ads, no account, no data collected.

Decibel Meter is an accurate, honest sound level meter for iPhone. Measure noise in decibels with A-weighted dBA readings that are free and on by default, calibrated per iPhone model, typically within ±3 dB of a professional meter. No ads, no account, no data collected.

Whether you need to check noise from a loud neighbor, measure sound at a concert, see how loud your workplace is, or check how loud the nursery gets, Decibel Meter gives you a fast, honest answer.

ACCURATE OUT OF THE BOX
• Real-time decibel readings with a smooth, easy-to-read gauge
• A-weighted (dBA) measurement free and on by default, matched to human hearing
• Calibrated per iPhone model, with a free calibration trim to match a reference meter
• Honest accuracy: typically within ±3 dB of a professional sound level meter
• Clear warnings when a reading can't be trusted (like an uncalibrated headset mic)

EVERYTHING ON ONE SCREEN
• Live dB level, Peak, Min, and true Leq average
• Rolling time chart of your measurement
• Color-coded loudness zones from quiet to dangerous, with haptic feedback
• Plain-language references: whisper, conversation, traffic, concert, jet takeoff

PROTECT YOUR HEARING (PRO)
• NIOSH and OSHA noise dose tracking: see the % of your daily safe exposure
• Safe listening time: know how long you can stay before it's too loud
• 8-hour TWA projection for workplace-style awareness

ANALYZE SOUND LIKE A PRO (PRO)
• Real-time frequency spectrum analyzer with 1/3-octave bands (25 Hz to 16 kHz)
• A, C, and Z frequency weighting (dBA, dBC, dBZ)
• Standard Fast, Slow, and Impulse time weightings

SAVE, EXPORT, SHARE
• Save snapshots of any measurement with one long press (3 free, unlimited with Pro)
• Unlimited history and CSV export with Pro
• Share readings as clean images (watermark-free with Pro)

BUILT FOR iPHONE
• Live Activity and Dynamic Island show levels while you multitask
• Home and Lock Screen widget with your last reading
• Control Center control (iOS 18+) and Siri Shortcuts ("What's the sound level?")
• Full VoiceOver accessibility, dark mode, and iPad support

PRIVATE BY DESIGN
• No data collected. Ever.
• Sound is analyzed live and never recorded, stored, or sent anywhere
• No account, no ads, no tracking

FREE VS PRO
The core meter is free forever: accurate dBA measurement, Fast response, live chart, stats, and 3 saved snapshots. Decibel Meter Pro unlocks C and Z weighting, Slow and Impulse response, NIOSH/OSHA noise dose, the frequency spectrum analyzer, unlimited history, CSV export, and watermark-free sharing.

Pro is available as a weekly or yearly subscription, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Note: iPhone microphones are not certified measurement instruments. Decibel Meter is designed for awareness and everyday measurement, not regulatory compliance.
