Wonder Decibel turns your iPhone into a portable acoustic lab: precise decibel readings plus plain-language noise levels—from “Quiet Library” to “Hazardous Noise”—so you know when to act, not just what number flashed on screen.
Switch between dBA, dBC, and dBZ weightings for real-world jobs, watch waveform, FFT, and spectrogram views, log sessions with GPS and notes, capture photo/video proof with live SPL overlays, and export polished PDF reports for safety, venues, or neighborhood documentation.
