BUILT-IN CALCULATOR
Do the math without leaving the app. A full on-screen keypad lets you add, subtract, multiply, and divide your values before converting — no need to switch to a separate calculator app.
MAKE IT YOURS
Don't see the unit you need? Add your own custom units with your own conversion values. Reorder, rename, or hide any unit — built-in or custom — to keep your list focused on what you actually use.
LIVE CURRENCY RATES
Currency conversions update automatically once a day, so your exchange rates stay current without any effort on your part. Turn auto-updates off anytime if you'd rather manage it manually.
YOUR FORMAT, YOUR RULES
Choose how many decimal places to show, and pick your preferred decimal and grouping separators to match how you read numbers.
LIGHT, DARK, OR SYSTEM
Match your device or pick the look you prefer — the whole app adapts instantly.
Simple, focused, and built to get you the right number fast.
