We have created the iOS App for all Apple devices. This App can be a useful tool in the identification of substances. There are two tabs at the bottom of the app, Reagents and Substances. If you select “Reagents,” you will be provided a list of reagents. Upon selection, a new screen will open with all the reactions you may expect from that particular reagent. If you select “Substance,” a new screen will open with all the substances. You will then select a substance, such as LSD, and it will show all the reactions from different reagents for that substance.
