GradePin Drainage Layout
Plan Drainage Grades & Stakes
$9.99 · Designed for iPad. Not verified for macOS.
Turn field elevations into a buildable drainage run: design profile, cut/fill, reverse-grade checks, and readable stakeout cards—offline.
GradePin is a focused field-grade planner for landscapers, drainage installers, site crews, and contractors who need a short run to fall the right way.
Record stations with existing and design elevations, datum, minimum slope, and site notes. The grade sheet calculates cut or fill at every point. Profile view compares existing ground against the proposed line and flags reverse-grade segments before work begins. Stake cards carry each station and design elevation to the work face in a large, readable format.
GradePin is an estimating and planning aid, not certified survey software or a substitute for site verification, engineering requirements, codes, drainage design, or trained judgment.
Records stay on the device. There is no account, cloud sync, analytics, advertising, tracking, subscription, in-app purchase, AI processing, or backend upload. One purchase unlocks the complete tool.
