### 3/5 — Alright but forcing me to share an app I payed for is stupid.

*2026-08-08, version 2.1.4*

App is helpful, but wouldn’t let me use it until I shared and rated. And even then wouldn’t let me use it, very disappointing.

### 1/5 — 差评

*2026-06-10*

垃圾，付费软件，还不支持中文

### 5/5 — Best tool for fitter welder calculation

*2024-01-17, version 2.1.4*

If you used old school for calculation maybe this tool is not for you. It get used to few try here and there before you feel ok to know how it worked, if you are self teaching with experience  you don’t need tutorial for this or any manual

### 2/5 — Pop review constant

*2022-09-09, version 2.1.4*

The leave a review constantly pops up

### 4/5 — No to bad

*2021-07-01, version 2.1.4*

app is fairly accurate about a 16th off.. doesn’t do equal spread offsets or parallel so a little let down.. the app they have that does do it doesn’t work on iPhone so there’s that also..

### 1/5 — Either I’m missing something or this app doesn’t work for advanced rolling offsets

*2021-04-27, version 2.1.4*

This app gave me the wrong cut length and travel length. I’ll stick to the old school way and work the formula. There is an 8” difference in the cut length.

### 3/5 — Lacking

*2020-12-07, version 2.1.4*

Should add a parallel offset section. 
The app takes a bit to het used to. 

Also, it needs an option to use Victaulic fittings.

### 4/5 — Cool

*2020-11-22, version 2.1.4*

Works

### 5/5 — Great App

*2020-11-20, version 2.1.4*

This app works great!  But no longer work with IOS 14.2. Won’t even open

### 5/5 — Works great

*2020-11-10, version 2.1.4*

Works perfect when you take time to figure the basics out
