Sono is a clean, easy-to-read sound level meter that turns your phone into a real-time decibel meter. Measure how loud anything is, right now, in dB(A). No sign-up, no login, fully offline. Checking a noisy restaurant, a concert, your AC or PC fans, road and traffic noise, a snoring partner, a baby's room, a workplace or machine shop, or a neighbour's music? Sono shows the sound pressure level (SPL) instantly with a clear live reading, an animated dial, and a scrolling graph. Why Sono • Fully offline. No account, no login. Your audio is never recorded or stored and never leaves your device. • Live dB(A), min / average / max, real-time graph, history and calibration, included. • Honest readings. A per-device calibration offset lets you trim the reading to match a reference. Features • Live decibel meter with a large, easy-to-read dB number • A, C and Z frequency weighting: dB(A), dB(C), dB(Z) • Min, average and max for every session • Real-time scrolling graph, from 30 seconds up to 30 minutes • Peak hold marker on the dial • Session timer with pause and resume • Calibration offset to match a reference level • Three gauge styles: circular, semicircular, and analog needle • Reference guide: how loud common sounds are, from a whisper to a jet • Save measurements with labels and notes, then browse your history • Add timestamped marks while measuring • Dark mode that remembers your choice, plus optional haptics • Lightweight and fast, opens straight to a live reading How Loud Is It? Quiet library ~30–40 dB · normal conversation ~60 dB · busy traffic ~70–80 dB · lawn mower ~90 dB · nightclub ~100 dB · rock concert ~110 dB. Sono labels the live reading against everyday sources so the numbers actually mean something. Great For • Checking whether a venue, restaurant or workplace is too loud • Settling neighbour noise disputes • Calibrating speakers, home theatre and audio gear • Measuring appliances, fans, engines and machinery • Anyone curious how loud their world really is A Note on Accuracy: Phone microphones are tuned for voice and can clip at very high volumes, so readings are approximate. Sono is a reference tool and is not a replacement for a certified sound level meter (SLM). Use the calibration offset to align Sono with a known reference for more reliable results. Sono is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Not a certified sound level meter, for reference only. Sono: the simple, offline decibel meter.

Verdict
The clearest difference is ads: Atom8 at none against Sound Level Meter's shown. Sound Level Meter's advantage is update cadence (every 11 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
