Heartthrob is a unique application that animates a large red or pink heart on the screen. When the screen is tapped or you shake your iPhone, the heart begins to expand and contract, playing either a heartbeat sound or a favorite song from your library. Tap on the heart again to stop the beating and pause the music. Rotate your iPhone to display the heart in landscape mode.
Slip it in your shirt pocket to get someone's attention, or place it near a gift to surprise that special person with a beating heart or your favorite song. This is a perfect conversation piece for Valentine's Day or to spice up a date.
