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! :)

Does not do a thing

It says I do NOT have internet when everything else on my pad, that is on internet WORKS. Plus they never answer emails. Do Not buy or get until fixed.

Developer Response ,

Dear Ldwarrior1, Seismometer is not using any internet connection other than to read help. Please test it again. And please send an email again as there is none received by your name "Ldwarrior1". Thank you.
