I notice that the Royal Society of Chemistry have just added another mobile app, the Periodic Table is based on the Periodic table on the RSC website and contains lots of interesting facts about the elements.

There are actually a few other Periodic Table apps, including Molar, EleMints, Periodic Table of the Elements, Merck PTE HD, The Chemical Touch, The Elements and my favourite The Elements in Action.

The Elements in Action has videos describing the elements, so if you have ever wanted to know what happens when rubidium is dropped into water this is the app for you, bear in mind however it is a 557MB app.
