## Most critical reviews (8 lowest-rated)

### 1/5 — Garbage

*2019-06-21*

Doesn’t work on my iPhone X because the calculate button is covered by the ear mic. Therefore not able to calculate anything. Needs update bad!!

### 1/5 — Calculate button obscured on iPhone XR

*2019-02-21, version 1.1.0*

Won't work with an iPhone XR as the calculate button is obscured by the phones earpiece

### 3/5 — Mean diameter

*2013-11-27, version 1.0.0*

This app would be more accurate if there was the option of using the mean diameters I.e. centre lines on the thickness of the material. I make cones on a regular basis and flat patterns must be calculated using the mean diameters to achieve the correct finished size.

### 4/5 — Fantastic and easy to use app but...

*2019-12-13*

I have used this quite a few times with excellent results, but the issue I have had is that on the new iPhones, hitting the “Calculate” button is extremely difficult to do, almost impossible. If this was updated, 5 stars

### 5/5 — Cool tool

*2024-03-10, version 1.2.0*

Every now and then you have to make reducer in the field, this app would of been helpful a few weeks ago to figure out the math on the fly. 
Looking forward to to next time.

### 5/5 — Works great!

*2021-12-29, version 1.2.0*

In developing a stove hood that uses cones this application helped out.  It’s right!  Thanks.  PS: note the big calculate button up top.

### 5/5 — Worked great until I got a new phone.

*2020-07-13, version 1.1.0*

Just got the iPhone 11 Pro.  I can’t get the calculate button to work.  If you see this can you look into it.  This app makes life easy when I can use it.

### 5/5 — Fabricator

*2013-12-28, version 1.0.0*

This app is easy to use and incredibly useful for a quick and easy layout of concentric cones for the metal fabricating industry. It even has a built-in plate optimizer so you can tell how many parts you can get out of a user-definable sheet size. Well-done.
