Can you please add Mercalli scale?

Developer Response ,

Hi! Seismometer app provides you information on 4 major scales: Liedu, Shindo, USGS, Mercalli. You just tap on the little button on the right called "Scale", or on the name itself on the center of the screen. Please adjust your rating. You can always contact support by sending an email within app. Thank you! :)

It doesn’t do anything!
Last night we got a intensity 4 or a shido 3
It was super terrifying. I thought they were warn or something. all it does is it tests for some reason

Developer Response ,

Hello, I am really sorry to hear that you were terrified from the earthquake. Was the app monitoring for earthquakes? Did you press the play button after you have set up the intensity and the scale? There is a specific procedure that is outlined in the app’s help and in the app’s website. Please make sure you have done all that and please remember that you can always contact support within the app. Thank you
