I did what it said to "remove ads" that didn't work. Couldn't help but hit an ad button when trying to use this thing moving in and out of the menu. The ads were like some kind of a game flashing around on the screen popping up in different places. Migraine city! I really wanted it to work too! Bummer. Very disruptive Ads. I cannot get to the correct answers below Yes English. YES, spent a bit of time watching ads to get to my 50 coins so it would remove ads. Below does not show correct answers.

There is no point offering a sound / dB meter that does not have the ability to calibrate it. This sensitive App does and calibration is very easy. Simply place 3M from a device with a known (and trusted) output and adjust the reading to match. I would prefer a full-screen option allowing finer readouts from the 'needle' display but there is a precise digital display as well. Ads not too intrusive but, as the best meter app by a large margin, it's worth paying to remove them if used a lot.

By the time I managed my way through the add screens, there was no use anymore. Uninstalling.
