## What is WumouKleern?

WumouKleern is a landscape workbench of two precise, fully offline calculators. Swipe between them and every answer updates the moment you type.

Grade Bench keeps your marks in order. In Weighted mode you list each category with its weight and its score, and it returns your overall course grade with a letter. Switch to Final and enter your current grade, how much the final exam is worth, and the mark you are aiming for — it works out the exact score you still need. GPA mode totals your courses by credit hours and letter grade to give a cumulative grade point average on a 4.0 scale.

Slope Bench handles the geometry of a build. Give it a total rise and run and Stair mode lays out the step count, riser height, tread depth and stringer length. Ramp mode turns a height and a slope ratio into a ramp length and angle. Roof mode reads a rise and run as a pitch, angle and rafter length — each shown on a live dial.

Save any result to your history, reopen it later, and share it as plain text. Choose inches or centimetres and set your decimal precision in settings. Nothing is uploaded; every figure stays on your device.
