## What is Cento?

Cento works out any percentage in two seconds. No clutter, no annoying ads: you type, the answer appears.

FOUR CALCULATORS, ONE APP — ALL FREE
• Simple percent — what's 15% of 1,200?
• Increase — salary, tips, VAT in one move
• Decrease — the real price after a discount or sale
• Change — what percentage between two amounts?

BUILT FOR EVERYDAY LIFE
Shopping and sales, restaurant tips, a pay rise, VAT, how an investment performed… Cento covers everyday percentages.

FAST AND CLEAR
• Instant result as you type
• Shortcuts (5%, 10%, 20%…) to go even faster
• Plain-language explanation under each result
• Copy or share in one tap
