Coin flipping, or coin tossing is common in many sports, to decide who gets the choice of bowling or batting first in cricket games, or which team gets to play first, in soccer.
With digital currencies, and no need for coins, your watch can provide the same utility should you find yourself in the need of coin flipping!
This app lets you flip a coin in all its glory, including the old roman way: navia aut caput ("ship or head").
As a bonus, theres a 1 in 6000 chance that the coin lands on its side.
You can also decide to have a random number appear when tails is selected.
Statistics of which side gets picked are also available, in order to confirm that, with time (and tosses), it should tend to the same number of heads, and tails.
