## Most critical reviews (8 lowest-rated)

### 1/5 — Garbage

*2019-10-16*

Most of the formulas don’t work, kind of disappointed as it would be a handy app for displacements or spotting lcm but like I said, formulas don’t work on my phone.

### 1/5 — Please update

*2018-10-18*

Needs to be updated. Not enough casing sizes.

### 1/5 — Save your money

*2016-09-22*

Inaccurate and difficult to use. Don't try and contact developer from app, my second wife is more helpful and responsive.

### 1/5 — Waste of money

*2014-12-29*

I want my money back. Payed $12 for this app and the displacement calculations aren't even right. Says 5 1/2 23 ppf casing bbls/ft is 0.00820. Way off. C'mon man

### 1/5 — Soooo not worth it

*2013-03-15*

It's fun to play with while watching the guys pull pipe or when logging but not allot of things I can use on a day to day basis. My free well control data book and a calculator are WAY more useful

### 1/5 — Essential

*2012-05-11, version 1.6*

Not worth it. App does simple calculations that can be done on calculator and has no value tables.

### 4/5 — Weight

*2016-02-24, version 2.1*

Should add KG/M3 for fluid weights.

### 4/5 — wrong!!

*2012-04-03*

the bottoms up calculations are completely WRONG!!!!
