SAP values can vary slightly between calculators since they come from different sources. Your numbers will be close but may not be identical. Both tools use published SAP data — small differences are normal and expected.
No. The core concepts are the same — oils, lye type, water method, superfat. The interface is different, but if you've used SoapCalc, you already understand how a soap calculator works.
Yes. Add the same oils and percentages, set your water method and superfat, and you'll get equivalent results. You can also snap a photo of a printed recipe or screenshot to import it automatically.
You don't have to re-enter them by hand. Print or screenshot your SoapCalc recipes, then use photo import to bring them in — the app reads the oils and percentages automatically. You can also rebuild recipes manually if you prefer. Either way, your recipes are saved in the app once they're in.
Yes. The calculator, lye and water calculations, recipe properties, predictions, oil profiles, and fragrance calculator are all free. Pro removes the limits on Blend Advisor, photo import, and recipes — but you can make great soap without it.
