## Most critical reviews (9 lowest-rated)

### 1/5 — No work

*2025-02-14, version 1.15*

It stopped working from one moment to the next and it never worked again.

### 1/5 — Doesn’t work

*2023-06-21*

When you try and convert springs it doesn’t work

### 1/5 — Terrible app

*2022-01-02, version 1.15*

Bring back SSC Engineering app.  That app was much more feasible and convenient to use. This app isn’t very good.  Don’t like it whatsoever

### 1/5 — Does not work

*2021-09-24, version 1.15*

Maybe it works on the iPad, it doesn’t work on the iPhone. Unable to enter a door weight it will accept. Of course there is also no help to see if there is particular way it had to be entered before it accepts the entry.  Was it tested at all before last release?

### 2/5 — Cannot see output

*2022-04-29, version 1.15*

The output of calculations won’t show up. On one screen, you can click to request a quote. That will show the output. 

The adjustable cycle count doesn’t have labels. There is no adjustment for how much high lift. 

Not very useful due to the display issues

### 2/5 — Marginal Usability

*2018-05-07, version 1.0.4*

This app needs an update. Not particularly convenient to use.  Maybe it worked okay when it first came out, but my phone has current IOS 11.3.1, and it doesn’t work so well. And why is the weight deleted when I click to configure the springs. It’s also annoying when the numeric keyboard doesn’t easily get out of the way when I’ve entered the springing weight.  Having the window scale to my screen size would be nice.

Two stars because if I have to use it, I can still get information out of it.

### 3/5 — Can’t adj cable length

*2020-12-07, version 1.15*

Needs some more upgrades.

### 4/5 — Dark mode

*2020-09-27, version 1.15*

This a really helpful app. The only downside is if you have your iPhone on dark mode you won’t be able to see the fonts on the app. I hope developers can fix this bug.

### 5/5 — Worked great -

*2022-02-20, version 1.15*

Terminology took a little while to figure out, but the app was great
