Sound Level Meter

By itself, the analog meter really could be a little bigger,space for that. Apart from that,the first experience is quite good.

This sound level meter is fairly accurate from 30 to 85dB, once calibrated against a professional meter. Most phones have a microphone limit of 85-90dB; in my case, the SGS8's microphone doesn't detect sound levels above 85dB, and sound levels less than 20dB are virtually silence, so the working range is 30-85dB. The pointer is steady, but the graph line is a bit jittery. It has an easy-to-use calibration slider. There is a reset button. It has vertical & and horizontal modes, though in the latter you have to scroll between meter and graph, so vertical mode is more useful. It lacks a pause button, and the graph's y-axis is too short, squeezing the working range of 30-80dB into only 13mm, making reading levels difficult, especially without a pause button However, it is fairly accurate and free. Try this one.
