ChemSpider Mobile was an app developed by Molecular Materials Informatics Inc1 on behalf of the Royal Society of Chemistry to allow users to explore the benefits of ChemSpider on mobile devices. Since its launch we have made improvements to ChemSpider.com, including responsive design elements to allow it to work better on smart phones and tablets2 and upgrades to the ChemSpider web services3 that power it. As a result of these developments we felt it was timely to review the community’s need for the app and have taken the decision to discontinue support for the services that power the app from 31st October. We would like to thank everyone who used and provided feedback on the app to aid its development and encourage you to switch to using ChemSpider.com for future mobile use.
