Features
A fast, fully offline unit converter built for everyday use.
15 categories
Length, weight/mass, temperature, area, volume, speed, time, data (KB vs KiB handled separately), energy, pressure, angle, power, fuel economy, cooking (grams ↔ cups/spoons by ingredient density), and clothing/shoe sizes. Any category can be hidden from the grid in Settings.
Display modes
Switch between "from → to" for a single conversion, "one to all" to see every unit in a category at once, or parallel input in two fields for back-and-forth editing.
Custom keyboard
A dedicated inline keyboard replaces the system one, with a one-tap swap button and haptic feedback.
Human comparisons
Length, weight, and volume conversions include a relatable real-world comparison to make the number easier to picture.
Spotlight search
Find any unit by name in any of the interface languages, accessible from every screen in the app.
Favorites & history
Pin frequently used conversion pairs as favorites, and revisit your last 20 conversions without redoing the math.
