About this app

Measure sound, track noise, and protect your hearing with precision. 🎙️

Pixel Pulse transforms your device into a professional Sound Level Meter (SPL) and Noise Dosimeter. Wrapped in a stunning Material You interface, it offers the most beautiful and intuitive audio analysis experience on Android.

✨ COMPLETELY FREE CORE FEATURES Unlike other apps, we don't hide essential tools behind a paywall.

● Professional dB Meter: Visualise sound levels instantly with our responsive, expressive gauge.

● Unlimited Session Recording: Record, save, and replay as many audio sessions as you need. No limits on duration or quantity.

● Interactive History: Review past recordings with detailed stats (Min/Avg/Max). Scrub through waveforms to pinpoint the exact moment a loud noise occurred.

● Material You Design: A dynamic interface that adapts to your wallpaper's colours, supporting both Light and Dark modes.

● Privacy Focused: No audio is ever recorded or stored—only the decibel levels. Your data stays 100% on your device.
