## Description

Measure real-time decibels with min, average, peak, spectrum, and spectrogram, plus plain-language guidance on whether a room is loud enough to harm your ears.

Sonance turns your iPhone into a beautiful, instant sound-level meter — and makes a raw number actually mean something.

Point it at the world and watch a high-fidelity decibel gauge swing in real time, see the room's frequencies dance across a live spectrum, and get a plain-language read on whether what you're hearing is safe for your ears. No setup, no sign-up, no waiting.

No ads. No account. Nothing leaves your phone.

— A METER THAT LOOKS AS GOOD AS IT MEASURES —
• A dramatic, animated decibel dial with a smooth needle and crisp readout
• Live MIN / AVG / MAX / PEAK so you can capture a moment or watch a trend
• Six hand-tuned themes — Aurora, Inferno, Mono, Neon, Ocean, Sunset — pick your vibe

— SEE THE SOUND —
• A real-time frequency spectrum that reacts to every voice, beat, and rumble
• A scrolling spectrogram heat-map — time, frequency, and intensity in one stunning view
• A / C / Z frequency weighting, the way real sound meters work

— KNOW WHEN IT'S TOO LOUD —
• Clear hearing-safety guidance based on the NIOSH limit (85 dBA for 8 hours)
• A live "safe listening time" estimate as levels rise
• A reference ladder of everyday sounds — "≈ city traffic," "≈ rock concert" — so the numbers click

— A REFERENCE LIBRARY IN YOUR POCKET —
• Pure 1/3-octave test tones, a full 20 Hz–20 kHz sweep, and white / pink / brown noise
• Calming ambience beds — rain, traffic, café — to compare and demo
• A 1 kHz reference tone to help you calibrate against a known meter

— PRIVATE BY DESIGN —
Sonance works 100% on your device. The microphone is used only to measure sound in the moment — audio is never recorded, saved, or sent anywhere. No accounts, no tracking, no network. Ever.

Great for noisy restaurants, concerts, the gym, power tools, a baby's room, a too-loud AC, a home studio, or just satisfying curiosity about how loud the world really is.

Note: iPhone microphones aren't laboratory instruments. Sonance shows an estimated SPL and includes a calibration control so you can dial it in. Hearing-safety figures are educational, not medical advice.

Built for fast, private sound checks wherever you are.

New in 1.1: Saved-session field reports summarize total measurement time, estimated equivalent level, highest peak, projected dose, time-left estimate, and CSV export. Reports are numeric only and contain no audio.
