Garbage

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.

Save your money

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

Waste of money

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
