Most Useful

While this periodic table lacks the bling of some of the other periodic table, it is the only one that provides quick reference to the most commonly used items on the table. This makes it by far the most useful one available for quickly referencing molar masses. In addition to the general table, that can be pinched to zoom, press and hold gives access to more general info.

My only problem with the table is that is is little more than a scanned image of someone elses table. This causes pixelation at high zoom and should be replaced with a vector version, but more seriously I question whether the developer actually has permission to use the image.
