So far I like it.

I feel like my feed back is somewhat limited in value since I just began CP soap making. With that out of the way, I have enjoyed this app as it helps me better understand how the characteristics of each oil effects my recipient. It has caused me to learn more about the acids and the qualities of soap in general.

I do have some enhancements I would like to request.
1) It would be handy to view the qualities of each oil in isolation. For example, what values does Shea Butter, as a stand alone oil, have for each of the qualities and acids?
2) it would also be nice to compare 2 or more recipes side by side in a table format. Starting with ingredients, followed by qualities, followed by acids. All in the same tab so you don’t have to jump from tab to tab. This would also be handy to compare the quality and acids of specific oils (see 1)

I do also wonder where the values for the soap qualities come from? Qualities like conditioning and creaminess, what is the approach that is used to assign a number to that value for each oil?

All in all, I think this is a very handy tool, and I have yet to explore the record keeping functions.

I don’t like to do reviews due to it being time consuming but this app is too good not to. I stumbled across this app and at such a good time. I own a business and create soaps as one of my product lines. I needed to create reliable formulas and was searching for an app for a year now to help me out. Thank you, thank you for this app. Works perfectly and my soaps are better than ever!!! I highly recommend this app to anyone looking to create a good recipe with great results. I even love the feature where after I create my recipe, I can print it directly from the app to my printer. WORTH EVERY PENNY!!

Great app! More than just a recipe calculator!

I’m really enjoying this app. It has a great soap recipe calculator, but also has the ability to log batches that you’ve made with notes and pictures as well as a cure notification alert system. The developer is great as well. I had an issue with something not working correctly and he was quick to push out an update to fix my issue.
