## Most critical reviews (4 lowest-rated)

### 1/5 — Big flaw

*2024-01-28*

The program works beautifully.  But it doesn’t tell you that you’d better write down or screen capture everything. Because what you SAVE will disappear. After capturing and saving all the info at my granddaughters home on two occasions after a month I went to make curtains and all my data was GONE. (I am a programmer .. I know how to save files)

### 1/5 — App do not accept measurements in CM or MM

*2021-08-04*

Can not entree measurements in CM or MM. please update this. I bought this App in store but can not use🤦🏻‍♂️

### 1/5 — Wrong measurement units

*2019-03-28*

This app would be everything I’m looking for if I could configure the measurements. I’m in Australia and we work in cm/mm not inches

### 5/5 — Doesn’t make sense.

*2023-08-14*

I have tried to follow the help button, it whips through each page faster than you can read. 
There is no actual instructions that I can see. 
You think you are saving something but you aren’t. 
Very confusing app. 

I couldn’t find a way to convert to metric 
Just a very strange app. 
Would be happy to be proved wrong. But not without proper explainers.
