DanceStepper Free

Did you ever stand on the dance floor and had to ask yourself: "which foot comes first", or "how much do I have to turn on the third step"? That's what this app is for!

Look up detailed descriptions, step-by-step instructions, and animated diagrams for 10 ballroom and latin american dances and almost 90 figures and 18 suggested amalgamations.

Currently supported dances are: Waltz, Viennese Waltz, Tango, Quickstep, Foxtrott, Cha-Cha-Cha, Rumba, Jive, Samba, Paso Doble.

Note that this app is not meant to replace actual dancing lessons (because nothing can, really), but to supplement them and to serve as a reference and reminder.
The professional edition (DanceStepper Pro) costs a small one-time fee, but contains more dances and figures.
