"Isn't this too loud?" "What's the decibel level?" — hold up your phone and see instantly. SoundMeter uses your iPhone's microphone to measure ambient sound in real time. Beyond raw dB numbers, it labels every reading in plain English — "quiet library", "busy street" — so you understand at a glance. From noise dispute evidence to sharing concert loudness, one app covers it all. --- Key Features --- ■ Real-Time dB Meter A half-circle arc meter shows the current volume at a glance. Updated every 100ms with smooth animation, plus MIN / AVG / MAX statistics to track changes over time. ■ Plain-English Sound Labels 30 dB "Quiet Library", 60 dB "Normal Conversation", 90 dB "Very Loud" — 11 levels of intuitive labels help you feel the volume beyond the numbers. ■ Session Recording Tap "Start Recording" to save a session. Automatically logs 1-second dB samples, start/end times, and optional location tags. Perfect for documenting noise disputes. ■ Time-Series Charts Swift Charts area graphs visualize your entire session. Color bands in the background instantly show quiet zones vs. warning zones. ■ CSV / PDF Export Export session data as CSV or PDF. Ideal for attaching to complaint filings, emails to landlords, or property manager reports. ■ Noise Alert Notifications Set a threshold (30–120 dB) and get notified when exceeded. Choose "every time / every minute / every 5 minutes" — perfect for baby sleep monitoring, construction watch, or concert level checks. ■ Mic Calibration Offset Manually adjust for your iPhone's mic sensitivity (±7 dB between models). Compare against a professional calibrated meter for higher accuracy. ■ Location Tags Add location tags like "Downtown Apartment" to each session. Great for scouting apartments or comparing multiple locations. ■ Share Cards Turn your current dB reading into a shareable card for X or Instagram. "Front row: 105 dB" — bring the experience to your feed. ■ Widget Support Home Screen widgets show your last measured dB and label. Lock Screen widgets supported too. ■ iCloud Sync Session records sync automatically via iCloud. Switch devices without losing history. --- Perfect For --- ・Documenting noise complaints from neighbors ・Scouting apartments for ambient noise levels ・Checking a bedroom's quietness for a sleeping child ・Measuring sound leakage during music practice ・Sharing concert or festival loudness on social media ・Recording construction noise for property management ・Verifying quiet cafés for focused work --- Privacy First --- Your audio is never recorded or stored. Only dB values are captured — kept on your device and iCloud. No external transmission ever. --- Minimal Design --- Sage green aesthetic — calm, beautiful, grown-up. Not a garish tool, but a meter you're happy to keep on your Home Screen. Full light and dark mode support. --- More --- ・Full dark mode ・16 languages supported ・iCloud sync ・Remove Ads IAP (one-time purchase) ・All features free --- Disclaimer --- This app provides approximate measurements using the iPhone's built-in microphone and is not a substitute for legally certified calibrated equipment.

Verdict

The call
