DigiDrummer Lite is a free, simple drum simulator that lets you play eight different drums in a reasonably spaced, four-by-two grid using your touch screen. As with most musical instrument-emulator apps, the sound (using actual drum samples) is considerably better while using headphones or external speakers with subtle, fairly high-quality audio--although iPhone headphones are probably up to this free app's most likely use: namely, killing time and/or entertaining kids. More serious musicians should also check out the paid version of DigiDrummer and other similar apps, to get access to different drum sets, the ability to record, and more.
