This "app" is just a list of elements sorted by their names. There is no attempt to display and allow access to the element data from a periodic table, let alone from a list sorting them by their atomic number (which would be the second best way.) An app should really allow searching of all the data to take advantage of the whole point of the computer in a tablet.
Also, while there is lots of data, there doesn't seem to be any way to copy and paste those values to other apps. A simple text document with this info would ironically be more useful.
