PipeGrade: Pipe Slope Gauge

Turn your iPhone into a practical pipe-slope gauge for plumbing, drainage, sewer, and DWV work. PipeGrade helps plumbers, contractors, installers, and DIY users plan runs, measure grade, and keep organized field records.
Measure live slope with the motion sensors, calibrate flat and side-edge placements separately, check direction and stability, lock readings, and save them to a pipe run. Calculate slope, fall, horizontal run, or end elevation, then generate station and invert-elevation schedules. Organize projects with notes and field photos, and export field-ready PDF or CSV reports.
Supports metric and imperial units, including percent, degrees, in/ft, mm/m, and 1:X. Project data stays on your device unless you choose to export or share it. No account, ads, or subscription. An optional one-time Lifetime Pro purchase unlocks the complete workflow.
PipeGrade is a field calculation and documentation aid, not an approval, certification, or substitute for local codes. Verify final work using calibrated equipment and the methods required by your authority and project documents.
