About this app

SLOPE - PROFESSIONAL GRADE CALCULATIONS FOR SURVEYORS, ENGINEERS & CONTRACTORS

THREE POWERFUL CALCULATORS IN ONE APP

Slope Calculator Input Point A elevation, Point B elevation, and horizontal distance to instantly calculate elevation difference, slope as a decimal, and slope as a percentage. Perfect for grading plans, site analysis, and verifying field measurements.

Elevation Calculator Enter slope percentage, horizontal distance, and starting elevation to determine elevation difference and true elevations in both positive (upward) and negative (downward) directions. Ideal for planning drainage, roads, and accessibility ramps.

Distance Calculator Input slope percentage and elevation change to calculate the horizontal distance required. Essential for estimating project scope and material quantities.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
