Grade Slope Pocket

Catch costly grade mistakes before crews dig, trench, or set pipe. Grade Slope Pocket gives drainage, plumbing, and utility crews fast field answers for slope, fall, run, and invert checks on iPhone.

Use it to:

- check pipe slope and fall before excavation, bedding, or install starts

- solve fall from run and slope percent when you need a quick field answer

- solve slope from run and fall for drainage and utility layouts

- verify invert start-to-end difference before a bad grade becomes rework

- read percent, ratio, run, and fall with clear units while staying fully offline

Built for field crews who need on-site answers that prevent expensive mistakes, not generic classroom math.
