10 Figure (iPhone)
Your complete and utter lack of musical skill is no match for Figure. This 99-cent iPhone app lets you lay down a beat, garnish it with a bassline and top it all off with a synth melody and a pitch that responds to your touch. Getting your first track together is about as simple as it gets, but Figure features enough bells and whistles for you to cobble together the ultimate masterpiece — all of which is presented in a slick, bold and intuitive interface.
