Convertly

Convertly is a fast, fully offline unit converter that keeps everyday math out of your way. Switch between length, weight, temperature, volume, data, speed, area and time in a single tap — type a value on the built-in keypad and the result updates instantly.

Tap once to swap the two units, browse every category in a clean grid, or open a live reference table that shows one value across all units at the same time. Pin the conversions you use most for instant access, and revisit anything you calculated before in your history — tap any entry to restore it.

Make it yours: choose a light, dark or system theme, pick an accent color, and set how many decimal places you want to see. Everything works without an internet connection and nothing you enter ever leaves your device.

Whether you are cooking, studying, traveling, working out or just curious, Convertly gives you accurate answers in a clean, distraction-free interface. Lightweight, private and ready whenever you need it.
