What is this?

A bunch of apps that have no real functions. Infographics is more useful than these apps

This app STINKS!!!!!!!

Easy and handy

Nice little app to calculate molar mass of any formulae you want to invent. Handy way to assist students to remember where elements are on the periodic table too. Very easy to enter compounds like Al2(SO4)3 where numbers correctly appear as subscripts. A tap on the calculate button and it's all done! It also gives you a basic profile of each element. This however is all it does.
