Decent periodic table to quickly find the basics, the only problem is you need to sort a list to bring up the properties of the element. If the app changes so that you can just press on the element to get to its properties that would be much more efficient. For this reason alone I give three stars since it makes it more annoying than anything to get to the properties, would get 5 if this is fixed.
