About this app

An app that both converts units and works as a dictionary explaining what each unit means. Useful for everything from converting units in class to checking currency before a trip abroad.

■ A wide range of conversion categories
・Length, area, volume, mass, speed, temperature, angle, pressure, energy, power, force, density, fuel economy, data size, and more
・Includes lesser-known units too — traditional Japanese units, imperial units, nautical miles, carats, horsepower

■ Unit dictionary
・Search across unit names, aliases, and symbols
・Look up how a unit is pronounced, its rough scale, and fun facts
・Jump straight from a search result into conversion mode

■ Currency conversion
・Real-time currency conversion using up-to-date exchange rates

■ Built to be easy
・Conversion and dictionary lookups work entirely on your device (currency conversion needs a connection to fetch exchange rates)

■ AI support (Premium)
・Just ask the AI "what unit is this?" or "convert X to Y" — it handles switching categories and running the conversion for you

Good for: converting recipe measurements, studying science and math, or checking currency and units before an overseas trip.

■ Cloud AI support (Premium)
• Cloud AI assistance for app operations: up to 30 successful responses per day, resetting at midnight Japan time.
AI requires consent and an internet connection. AI may pause when the shared service budget is reached; unit conversion and dictionary lookup and subscription ad removal remain available.
