Noise Meter
Recordings with date and time
Noise Meter measures sound levels with your iPhone’s microphone and keeps the date and time with every reading. Record a whole night of noise, see Japan’s day and night noise standards on every chart, and share a card with the average and maximum. It never records audio: only the level of each second is kept.
Coming soon to the App Store.
