About this app

Delta is a fast, focused percentage calculator for the numbers you actually
run into — a price change, a sale tag, a tip, a raise, a savings plan.

Type two numbers and the answer appears instantly. No ads, no account, no
internet required.

WHAT YOU CAN WORK OUT

• Percentage change — the change from one value to another, with the
increase or decrease shown clearly and charted
• Projection — apply a percentage to any amount to see where it lands,
for growth or decline
• Discount — what a sale price really costs and how much you save
• Markup & margin — turn a cost price into a selling price
• % of total — what share one number is of another
• Compound growth — model savings and investments over years, including
regular contributions
• Tip & split — the tip, the total, and what each person owes
