Turn your iPhone into a smart sound measurement tool: measure noise, find frequencies, compare changes and create reports.
Most sound meters just show a number. Sound Meter tells you what it means and what to do next.
MEASURE
• Live dB with A, C and Z weighting and Fast, Slow or Impulse response
• Average (Leq), minimum, maximum and peak, with a 60-second graph
• Plain answers: "43 dBA · Quiet, like a library"
• Guided modes for Noise, Machine, Speaker and Room set everything up for you
FIND
• Spectrum analyzer with the dominant frequency and likely sources ("126 Hz · Low hum — check fans, compressors, fridges")
• Tap to pick any frequency, pinch to zoom, freeze and peak hold
• Find mode: lock a frequency, walk around and follow "Getting louder" to the source
COMPARE
• Save sessions and measure Before / After from the same spot
• See exactly what changed: "Noise reduced −8.5 dBA average, largest change at 125 Hz"
• Great for HVAC work, soundproofing, speakers, fans and machines
REPORT
• PDF measurement report with levels, graph, spectrum, events, device, microphone and calibration
• CSV data and PNG image export
MONITOR
• Set a threshold and get notified when noise stays above it
• Event log with times and maximum levels, even while the phone is locked
NUMBERS YOU CAN TRUST
• Calibration wizard: match a reference meter or acoustic calibrator in a minute
• Measurement Quality shows why a reading is Good, Fair or Poor — clipping, noise floor, microphone route, calibration
• USB measurement microphones and wired headsets supported
ALSO
• RTA in 1/1 and 1/3 octave bands
• Tone generator: sine, pink noise, white noise and sweeps
PRIVATE BY DESIGN
Audio is analyzed live on your iPhone. It is never recorded, stored or sent anywhere. No ads, no account, no tracking.
NOISE LOG FOR COMPLAINTS
• Monitor overnight (until 7:00) and log every time noise stays above your threshold
• Label each event — music, voices, footsteps, dog, traffic — and add a note
• See night-time events (22:00–07:00), the longest and loudest event, and how much of the night was actually measured
• Share a complete PDF noise log or CSV with your landlord, HOA or council
LOCK SCREEN & DYNAMIC ISLAND
• While a session or monitor runs, see the level, average and event count without unlocking — and stop it with one tap
READY FOR IPHONE DUO
• Two-column layouts on the large inner display
PRO — ONE-TIME PURCHASE
Find mode, Before / After, noise monitor, PDF and CSV export, 1/3-octave RTA, unlimited sessions, calibration for every microphone and the full generator. Pay once, no subscription.
Sound Meter is a measurement reference, not a certified sound level meter (IEC 61672). For legal or occupational compliance, use a certified instrument.
