Functional at best

App is OK - I find myself using the app to look at the molar masses of the atoms. What would make this app a 5/5 is if it had the ability to caculate the molar mass of the molecule you wanted to know.

My suggestion: input a command click function that will add the molar masses of each of the atoms clicked while command is held; display the command clicked atoms center screen, program a clear button.
