### 3/5 — A shame it’s only in English

*2020-07-21*

So many soap calculator out there are multilingual. kind of surprising this one isn’t

### 3/5 — Wrong Data for Palm Kernal Flakes

*2020-03-18, version 1.5*

The values for Palm Kernal Flakes are incorrectly entered. All of the values are shifted down one space starting with iodine. It looks like it has a 227 for lauric, which would be insane! Ruins all of the recipes that include this oil. Hopefully they will fix in an update soon!

### 2/5 — NOT thesame as soap calc

*2020-03-02, version 1.5*

I don't like it.   It does not allow me to caculate Lye to water ratio....  hard to read too.  I wish i did not made the purches.

### 3/5 — I can’t find a list of recipes I saved

*2019-12-11*

I just purchased the app, I love how it works and suggest the safer recipe however once I save recipe I can not go back unless I delete the data so I can add new one. You need to add a favorite list so we can save our own recipe and go back to it rather than screenshot each one. Thank you.

### 5/5 — Soap calc pro

*2018-10-23*

Love this App, quick and very simple to use, it's never let me down in years of cold process soap making.

### 1/5 — Just terrible

*2018-08-18, version 1.5*

I just got this and I can not recommend it. It only allows you to calculate water as % of oils (which isn’t a good idea to begin with) and other numbers it recommends are outright insane. 
One of the things I do when looking at a soap calculator is I run simple, tried and true recipes I’ve used through it to see what happens. On a 2 pound recipe it recommended 100 oz of fragrance oil and 2 + pounds of water! 
Tl;dr: use the soapcalc website or do your own math. This app is bad

### 2/5 — App Support, Where Are You?

*2018-06-25, version 1.5*

App Support link does not work. I have a question about adding fragrance oil. Otherwise, app does calculate fine, I just don’t see where I can add the fragrance oils.

### 3/5 — Lye calc not accurate!

*2017-08-27, version 1.5*

This app doesn't factor in the 90% purity of KOH.  It will calculate less causing issues with dual lye soap recipes.  Please fix this issue.

### 1/5 — Don't waste your money

*2017-06-29, version 1.5*

This doesn't have any options for essential oils and the calculations are way off.

### 1/5 — Can't trust

*2017-04-03*

It's hard to trust a calculator that tells me I need 422g of fragrance for 650g of oils!
