This tip calculator on steroids gives you a simple way to split up restaurant bills with your friends. It is very useful for easy splits, and it even has a couple of features that would make it handy in more complicated situations.
One nifty feature is the option to adjust a person’s share up and down by a dollar at a time and distribute the balance among other guests, which is particularly useful when just a few people split an appetizer, for example. Splitsville will also let you calculate the tip into everyone’s share of the bill, provided you all agree on the quality of the service. The app only divides for up to eight guests, however, so bigger parties may have to work out a split bill the old-fashioned way: arm wrestling. Free, for iOS devices.
