Apollonius Software
Apollonius by Adolfo Rodriguez is an Interactive Geometry Software (IGS, or Dynamic Geometry Environment, DGE) for the iPhone,
iPad and iPod Touch. It allows you to make geometric constructions (such as those made using a compass and straightedge/ruler) and move their parts smoothly using the device's
touch screen.
Apollonius was inspired by similar software for personal computers, such as Cabri
and The Geometer's Sketchpad.
