Useless
This use to be the best when it was an offline calculator, now it needs a data connection to load.. unfortunately we work in the oilfield and usually don’t have one in the working area
Good when it works.
Used this app for a while. It was great. Last updates to IOS, it won’t even load. It’s useless.

Great for field work!
If you’re on the my pits and you need a quick mud mix calc, this app is amazing. That’s the main feature I use, being a mud engineer. And it’s usually right on the money within 1/10 of a ppg.
Keeps Kicking Me Out
When trying to use app it keeps kicking me out of app and back to the home screen.
