This app has got great potential to be a VERY useful tool for anyone making soap. There is a bit of a learning curve, but not a big one. The fact that it automatically calculates the exact amount of lye and water required based on an enormous inventory of oils and additives and their amounts, takes all of the guess work out of it. This is especially important because having a disproportionate amount of lye in relation to the oils and water can potentially make your soap so basic that it will irritate or burn your skin!
It has an easy conversion system, so you can select grams, ounces, or pounds, and Celsius or Fahrenheit.
It's also got an interesting feature that enables you to compile a recipe neatly into a report that you can then save as a picture to your phone.
I will add that the only obvious issue is that it would benefit from improved translation into English. Aside from that, there are so many other excellent features, and this will be my goto soap making app from now on.
Thank you to the developer!
