The experiment-diagram canvas
Draw the setup the way the mark scheme wants it
A quiet canvas with the lab drawn in — beakers, meters, clamps and cells as clean schematic symbols. Arrange, label, annotate; export crisp vector output or drop it straight into a Write report.
A palette of real lab equipment
Beakers, thermometers, burners, cells, bulbs, meters — schematic symbols that read like a textbook, not clip-art.
Move, resize, rotate — precisely
Every object carries clean handles, keyboard nudges, z-order and an inspector for stroke, weight, fill and rotation.
Crisp export
SVG and PNG output on white paper — ready for a printed report or a slide.
