Most of the apps from Molecular Materials Informatics have been updated recently, due to the iPad3: the retina-class screen has half again as many pixels as a 1080p monitor (i.e. a lot), and the performance profiles of some graphics operations have changed. A few things that were fast became slow, and so a few tweaks were necessary. A whole lot of apps got reviewed and passed in quick succession: MolPrime+, MMDS, MolSync, ODDT and ChemSpider Mobile. Others will follow soon.
