Tip calculator

tip calculator used to be a small but sometimes frustrating part of paying a restaurant bill. Diners had to estimate a percentage mentally, write numbers on a receipt, or use a basic calculator to work out the final amount.

Today, a few taps on a smartphone can handle the same calculation almost instantly. Modern tip calculators can determine the gratuity, add it to the bill, divide the total among several people, and sometimes provide different percentage options.

This seemingly simple tool reflects a broader shift in everyday technology: tasks that once required manual calculations are increasingly handled by specialized digital applications.
