MEASURE SOUND INSTANTLY
Point your phone at any sound source and watch the decibel level update live on a precision gauge, calibrated in dBA (A-weighted decibels) — the same weighting used by professionals to match how the human ear perceives loudness.

KEY FEATURES
• Real-time decibel meter with a smooth, easy-to-read gauge
• Min, Average (LEQ), and Max readings for every session
• Live waveform so you can see sound levels change over time
• A-weighting (dBA) and Z-weighting (flat) modes
• Adjustable time weighting for fast or slow response
• Built-in calibration to fine-tune accuracy for your device
• Session history to review past measurements
• Clean, distraction-free design that adapts to your screen

GREAT FOR
• Checking noise levels at work, home, gyms, restaurants, and events
• Monitoring loud environments to help protect your hearing
• Musicians, sound engineers, and AV setups
• Students and teachers exploring acoustics and physics
• Anyone who wants to know "how loud is that, really?"

A NOTE ON ACCURACY
Smartphone microphones vary by model and are not lab-grade instruments. dBing is built for everyday awareness and relative measurement, and the built-in calibration lets you align readings to a reference source for the best results. For certified, regulatory-grade readings, use a professional SPL meter.
