### 5/5 — 好用

*2023-01-09, version 1.5.0*

好用。但是iPhone14的系統更新後，有一些功能已經無法用了（設定、成本分析的價格設定）。有點可惜。希望作者可以更新。

### 1/5 — 千萬不要買的

*2021-07-05, version 1.5.0*

購買後, 發現有問題, 寄了三次信件給反應, 完全得不到回應, 建議不要購買
1• 荷荷巴油品(sf)輸入成本後, 在成本分析內出現的金額是零元,做超脂一樣是算入成本的

2•可以建議SF的字體顏色是紅色或有顏色嗎?   系統是顯示白色真的很不明顯

3•我的荷荷巴油是用來做SF(不列入基本油的%) , 但系統油品比率的%變成我的其它油品%分散了

4• 水量幾倍及鹼的計算系統有算錯了(超脂Sf就是不算鹼, 可系統就是算出有誤差值, 變成我只能用大概的倍數如2.2幾去做大概的調整)

### 1/5 — Not a soap calculator

*2021-04-23, version 1.5.0*

Do not pay for this app. It is not a soap calculator. There is very little useful info and none of what you see above is actually offered. Total waste of money and time.

### 1/5 — Waste of money

*2020-09-08*

Hate this app you can’t do anything with it

### 1/5 — 是個未完成的作品，而作者似乎也不打算完成他了

*2020-07-02, version 1.5.0*

太多問題了

### 1/5 — Boff

*2020-03-21*

Impossible de créer mes formules, ni de télécharger, car pas de code QR... 
Cette application n'est pas ce à quoi je m'attendais et ne m'est aucunement utile. 
De l'argent jeté par la fenêtre. ☹️

### 5/5 — 好用

*2019-11-11, version 1.5.0*

用了很多年，覺得非常好用，方便記錄做皂的配方。

### 1/5 — 沒有總重量

*2019-08-17, version 1.5.0*

沒有辦法用全部總重量來分配我油品的百分比

### 4/5 — 好用但是小地方瑕疵

*2018-11-12, version 1.5.0*

成本分析那邊，圓餅圖會到最下面蓋住成本數字，無法好好計算成本

### 5/5 — Soap studio

*2018-11-08*

I bought this app and after testing I found out very useful. I give 5 star because of everything works fine. I do not see any negative about this app. I have a few suggestions. I like each receipt to have its own oz or gram etc. When I start new I like to see new or add botton instead I have to click edit. I personally like this app. Very good job.
