888 Sport

888 Sport is a utility app that makes percentage math fast and foolproof, whether you're negotiating a salary, marking up a product, comparing sale prices, or splitting a bill with a tip. "X is what percent of Y?" is answered in seconds: type in a score of 43 out of 60 and 888 Sport tells you it's 71.67%, no formula required, no mental gymnastics. "Increase by %" handles salary negotiations and markup calculations: enter a base salary and a raise percentage, and 888 Sport returns the new value instantly, equally useful for VAT, profit margins, and price adjustments. The date and age calculator extends the practical value of the app: find your exact age in years, months, and days; calculate the number of days between any two dates; or count down to a future event. 888 Sport works entirely offline and needs no registration, all 10 tools are available the moment you open the app with zero configuration.
