RE SOUND METER How loud is your world? RE Sound Meter turns your iPhone into a real-time decibel meter. See the noise around you, understand it, and compare it to everyday references β from a whisper to a concert. WHAT YOU CAN DO Check how quiet your bedroom really is at night. See if your office is louder than a typical conversation. Measure how noisy your vacuum cleaner is. Find out if a restaurant crosses into the "too loud to talk" zone. Compare the sound of city traffic to a quiet park. Know when you reach the 85 dB danger zone during a concert. HOW IT WORKS A beautiful analog gauge displays decibel levels in real time, with color-coded zones from green (quiet) to red (dangerous). A live waveform shows audio activity instantly, while a 30-second history graph charts the noise over time so you can spot loud events as they happen. TEN REFERENCE LEVELS BUILT IN Wonder what 60 dB actually sounds like? Or whether your environment is closer to a library or a busy street? The reference panel tells you: - Breathing (10 dB) - Whisper (20-30 dB) - Library (30-40 dB) - Quiet Home (40-50 dB) - Conversation (50-60 dB) - Traffic (65-75 dB) - Vacuum Cleaner (75-85 dB) - Danger Zone (85+ dB) - Concert (95-110 dB) - Pain Threshold (120+ dB) DETAILED STATS Track MIN, AVG, MAX and PEAK during your measurement session. Useful when you want to monitor an environment for a few minutes and see how stable or chaotic the sound was. NO ADS. NO SUBSCRIPTIONS. NO ACCOUNT. Buy it once and it's yours forever. No pop-ups asking you to upgrade. No subscription nag screens. No login required. Open the app and it just works. FULLY OFFLINE The app never connects to the internet. Audio is analyzed in real time on your device and never recorded, never stored, never sent anywhere. No tracking, no analytics, no data collection. DESIGN A dark, minimal interface with a glowing analog gauge as the centerpiece. Built to look good and stay out of your way. IMPORTANT This app provides approximate measurements for informational and educational purposes. Smartphone microphones are not laboratory-grade instruments and readings can vary across devices. For professional, regulatory, or legal measurements, use a calibrated sound level meter. AVAILABLE IN 6 LANGUAGES English, Spanish, German, Japanese, Korean, and Arabic. Made by Resonancia Γter.
