I blend my own perfumes, so this app could be a huge help. There are some changes needed, though; and they should be pretty simple & straightforward:Having a database of only 32 oils just isn't enough. Sure, you can add your own, which is fantastic- but if you don't know the blend factor of the oil you're adding, it isn't much help. There are hundreds of essential oils, and this app is missing some common ones, such as basil. The essential oil database in this app needs to be greatly expanded. We don't commonly use cubic centimeters as a measurement in the US. We should be able to change the units of measurement to ounces or even teaspoons, since those of us who work with essential oils generally use these units. Think about including a recipe section for different essential oil blends, as well as a section for users to post their own favorites.This could be a 5-star app if these changes are made. Thanks!

This app doesn’t teach you how to use each essential oils, but it does what it intends to do and does it well - you input how much carrier oil you want to use, the percent dilution you’re aiming for, and the essential oil(s) you want to use, and it tells you how many drops of each EO you should use based on how strong each oil is.

I need an app to help me learn how to use essential oils. This was NOT it.

It would be a lot more helpful if it used oz (vs cc units) and if you could customize the dilution percentage instead of a few fixed amounts.
