True sidereal

True sidereal is how this app measures every chart: against the constellations actually behind the Sun, Moon and planets, rather than against the seasons. It uses thirteen bands of unequal width, Ophiuchus included, with boundaries drawn by the Midpoint Method. The sixty-four gates keep their equal size and their traditional order; only the frame they are measured in changes. A tool that reads the tropical zodiac can therefore give the same birth a different chart.
