About
See how loud your world really is. Decibel Pro turns your iPhone into a clean, color-coded sound meter. The animated gauge moves with the room. Quiet zones glow green. Conversation zones turn yellow. Anything that could damage your hearing pushes hard into red. You see the danger before you feel it. Built for people who care about real numbers. Live dBA readings update in real time. The waveform shows you the spike that just happened. Min, average, and maximum stats hold steady so you can compare a quiet bedroom to a loud cafe to a construction site without losing the moment.
