## Description

New: duplicate any tab into an independent copy — same numbers, separate from then on. In an app with a warm design, eight themes and a tab overview that stays smooth.

1+1 Calculator does the math and shows its work.

Most calculators hand you an answer and forget it. This one keeps a running tape on the main screen — every expression and every result, with correct operator precedence — so you can check your reasoning, catch the slip, and tap any earlier answer to bring it back down.

EVERYDAY MATH
• An always-on tape, so you see the steps and not just the total
• Calculators in tabs to keep separate jobs apart — name them, and each one works on its own
• A scientific mode with trig, logs, powers, roots and parentheses
• VAT / GST: enter net, tax or gross and get the other two instantly, at a starting rate you can edit
• Tip & split: enter the bill, pick a tip, split it across the table
• A memory bank for the values you keep reaching for

MONEY, LOOKING AHEAD
• Budget and trip-budget planners for what you actually spend
• An interest calculator that shows how savings compound
• A FIRE calculator to estimate your path to financial independence

MADE FOR iPhone AND iPad
• A warm, modern design with eight color themes
• System, Light or Dark, however you like it
• Two calculators side by side on iPad
• Hardware keyboard support, and a Control Center button to launch straight in (iOS 18 or later)

Free includes every calculator, one clean tab at a time. Infinity — a one-time purchase, or a monthly or yearly auto-renewing subscription — keeps every tab unlocked, gives you a tape up to 10,000 calculations deep, all eight themes, and two calculators side by side on iPad.

No ads. No tracking. No account. Just a fast, honest calculator.
