True Size gives you the same lightbulb moment in one clean click, built for the whiteboard so it reads from the back of the room, with nothing to close or scroll past. Being honest, it is the simpler of the two. Its advantage is that it lives alongside your quizzes, timers, group makers and 90+ other apps, all in one place, so it is right there in the lesson rather than a separate tab.
Open it, pick up a country, and slide it anywhere on the world map. As you move it, the shape resizes to keep its real area, because the reprojection preserves the true distances between points. Drag Greenland down to the equator and it shrinks dramatically. Drag a small equatorial country up towards the pole and it grows. It is a fast, visual way to show why a flat map is not the whole truth.
