The eJuice Me Up calculator is a fantastic vape juice calculator desktop tool for designing and filing eliquid recipes. It is one of the first projects of its kind made to assist DIY ejuice recipes. There are a lot of web applications out there. In order to have the ability to work offline, it is nice to have something installed on your computer desktop.
Another benefit of the program is its ability to calculate the cost to produce many different batch sizes, and to store a library of your flavoring on hand. Check it out!
