CheckSplit vs IntelligenceMesh

CheckSplit is a quick and simple calculator to determine how much each guest pays on an evenly-split restaurant check. Divide the check amount among up to 99 people and set the tip to any number to immediately see how much each person should pay with and without the tip included. Thanks to an elegant and simple interface, what was previously a chore now literally takes seconds. No more need for a clumsy calculator and history backtracking to figure out the details!
