Mobile Molecular DataSheet Updated
I just noticed that version 1.4.1 of the [Mobile Molecular DataSheet](http://itunes.apple.com/us/app/mobile-molecular-datasheet/id383661863) (MMDS) has just been submitted to the iTunes AppStore, and its notable new feature is the ability to select a datasheet and calculate structure-based properties. A new column is created for each selected property, and the calculation feature is applied to each row. The available properties currently include molecular weight/formula, log P, molar refractivity and topological polar surface area. The functionality is provided by the molsync.com webservice.
There is more information on the [Cheminformatics blog](http://cheminf20.org/2013/01/23/structure-property-calculation-with-mmds/).
There is a page of mobile science applications here.
