So far, I really like this app. Ive been using essential oils for 10 or more years and I still have oils I am not familiar with and some that I am familiar with that because they do so many things, I havent stored all of what they do in my brain. This app is a great quick reference guide. One draw back I see is that the EO list is so long it takes forever to get to the oil you want even though its in alphabetical order.
