About this app

ig Buddy is a drilling calculator and tally book built for the rig floor. Every calculation runs right on your phone, so it works out on location with zero bars.

Type your well in once. Casing, shoe, open hole and depth carry over to every calculator that needs them, so you aren't re-entering the same numbers on every screen.
