New math? Ha! Try kicking it "Old School" with Digital Abacus!

Learn addition and subtraction the old-fashioned way! Combining a “school abacus” (a simplified version of the ancient Chinese calculating device) with a digital readout, Abacus lets you challenge your friends to do math with nothing except beads on rods – then blow their minds as you whip through the same exercise, displaying your results in an easily-readable form!

Features:

# Showcase your iPad with a jumbo-sized abacus calculator
# Learn the lost art of the abacus, with the help of a digital readout
