OoshoO

Find out how noisy it is around you right now. OoshoO turns your iPhone into a professional noise meter and creates a map of the quietness of your city.

Too loud? Or perfectly quiet? OoshoO helps you understand the acoustics of the world around you. One tap — and you get precise decibel readings, your location, and a personal mark on the noise map.
A professional sound level meter in your pocket
Measure noise levels in real time using your iPhone's built-in microphone. An animated indicator and live dB scale show exactly what's happening to your hearing right now.
A map of silence and sound
Every measurement is automatically tagged with your location. Color-coded markers instantly reveal where you can work in peace — and where you'd better grab your headphones.
Your personal sound history — Daily average noise levels — The quietest and loudest spots you've visited
— Automatic background recording — Live Activities and home-screen widget support
Privacy comes first
