Coin Flip is the first ever truly random coin flip app for the iPhone and Apple Watch. The concept is pretty simple really, you shake your phone or tap your watch and the coin flips. You will see a cool video of a coin flip and then boom you have the answer to a question.WHY FLIP A COIN?DECISION MAKINGThe average adult makes 35,000 decisions per day (Source: Sahakian and LaBuzetta). Decision fatigue causes irrational trade-offs in decision making (Source: BaumeisterFlipping a coin or "Flipism" is a normative decision theory that prescribes an course of action with the minimum possible cognitive overhead to make the decisions. Truly rational decision-making requires a tremendous investment in information and cognition to arrive at an optimal decision. However, the expected marginal value of information gathered (discounted for risk and uncertainty) is often lower than the marginal cost of the information or processing itself. The concept of bounded rationality posits that people employ cognitive parsimony, gathering only what they expect to be sufficient information to arrive at a satisfying (or "good enough") solution. Flipism is therefore a perfectly rational strategy to employ when the cost of information is very high relative to its expected value.

This results in a 51% chance of the coin coming up as it started.APPLE PAYYou no longer need a physical money, and carrying coins is a pain.EVIDENCEThe Coin Flip app allows you to take a screenshot with a time stamp thereby providing evidence of an outcome that can be shared remotely.
