Very helpful

This is exactly what I was looking for. You can input your variety of oils and the app will tell you how much lye to use, with options for changing the superfat percentage. The app will predict the characteristics of your soap, and you can email the results to yourself to keep as a record. Others have commented on the app crashing, though I haven't experienced this yet. It would be nice if it allowed you to save your recipes for later tweaking or let you easily scale your recipes for batches of various sizes, but it is still a good tool.

Love it!!!!!

Love how you can substitute goat or regular milk for the water with wonderful results!!!! It makes beautiful milk soap that way!!!
Love how you can take an existing recipe and use the soapcalc and substitute things you have at home for things in recipe and have great results! Awesome when you are short an oil and need a substitute!!!
Can't say enough great things about it!!! Just have to think outside the box!!!
If I were to upgrade or change would be the lye calculated part....I would have it so when it went to calculate the recipe it changes the oil amounts so that the lye is easier to weight/ is harder to measure lye than it is to measure the oils....
example...if my recipe called for 16 ounces of oil and it meant .165 lye...then I would rather the results change the oil to 18.7 ounces and the lye to .7 ounces so the lye becomes an even number to weight......
Anyway I LOVE IT!!!!!!


Downloaded this app last week. Put in my desired amounts 2 or 3 different times and was happy to think I finally had a good tool to use. Now the app won't even open up for me to start using! What's up with that?!! Please fix whatever bug needs to be fixed! Glad I didn't waste money on the 'pro' version. I guess it's true what they say: you get what you paid for. I paid nothing and I'm getting nothing!!!
