iPad iOS apps - ChemDraw, Chem3D and CDSL have been withdrawn
PerkinElmer have announced that their iOS apps have been withdrawn.
Although PerkinElmer Informatics remains committed to making ChemDraw available to chemists everywhere, the iPad iOS apps ChemDraw, Chem3D and CDSL have been withdrawn from the Apple iTunes store effective immediately. The related Flick2Share capability is also withdrawn from service.
Whilst it was reported that there were plans to build an Android version in 2014 nothing has seen the light of day. It seems they are now focusing on ChemDraw Cloud.
If you already have ChemDraw or Chem3D installed they will continue to operate but the "flick2share" option will not function, it is unlikely that existing apps will be updated or supported in the future.
Alternatives for Chemical Drawing
There are a number chemical drawing apps alternatives to ChemDraw under iOS on the MobileScience Website. Perhaps the most popular is ChemDoodle Mobile and is provided to you for free when you purchase ChemDoodle desktop.
There are five main windows: Draw, 3D, Calculate, Spectra and Help. The Draw window shows a typical ChemDoodle sketcher, where you can draw and store your structures. The 3D window allows you to view the drawn molecule in 3D. The Calculate page calculates properties and the Spectra page simulates NMR spectra. All spectra are interactive.
Elemental is a free chemical drawing app from Dotmatics. This is actually the same chemical sketching application provided for all the Dotmatics products and as is used for drawing chemical queries in ChemSpider. It is also used int ElementalDB an iPad app that demonstrates substructure searching the 1.2M structure ChEMBL database locally on your iPad.
Molecule is a simple modern chemical structure editor. Allow to draw and share chemical structure. MF, MW, Monoisotopic Mass and Elemental Composition calculated interactively during drawing.
MolPrime+ is a chemical structure drawing tool based on the sketcher from the Mobile Molecular Datasheet from Molecular Materials Informatics, Inc. It provides a way to view and edit chemical structure diagrams on an iPhone, iPod or iPad. The unique and innovative sketcher is optimized for the touchscreen interface, and allows professional quality molecular structures to be drawn quickly and efficiently. The same drawing tool has been used in the Green Lab Notebook.
iMolecular Draw is an application that can view, edit and build molecules in 2D.
Chirys Draw chemical drawing app for publication-quality molecular structures and reactions. Designed from the ground up for the iPad, Chirys Draw takes advantage of unique multi-touch capabilities to make drawing molecular structures and reactions easy and accurate.
