## What is Convertly by WK?

Convertly is the simple, all-in-one converter and calculator built for everyday life.

No clutter, no sign-up, no ads getting in your way — just open it and get your answer in a tap.

EVERYTHING YOU CONVERT, IN ONE PLACE
• Currency — Live exchange rates for 16 major currencies (USD, EUR, JPY, GBP, KRW, CNY and more). Works offline with approximate rates, then refreshes the moment you're back online.
• Length — Millimeters to miles, and everything between. See every unit at once.
• Weight — Grams, kilograms, ounces, pounds, stones and metric tons.
• Temperature — Celsius, Fahrenheit and Kelvin. Tap "Use Current Temperature" to instantly pull the real outdoor temperature for your location.
• BMI — Metric or Imperial. Get your body mass index with a clear, color-coded health range.
• Tip — Pick a tip percentage, split the bill across any number of people, and round up the total. Perfect for restaurants and group outings.

DESIGNED TO BE FAST
• Live results — values update as you type. No "convert" button to press.
• One-tap swap between source and target units.
• Clean, native design that feels right at home on iPhone and iPad.

PRIVATE BY DESIGN
Convertly does not collect, store, or share your personal data. Location is used only to fetch the current outdoor temperature, and only when you ask for it.

Download Convertly and make every conversion effortless.
