Unit Switch is a professional unit and currency conversion app designed to deliver fast and accurate results. It includes converters for common and advanced units, an offline mode with daily rate cache, multi-language support (Spanish/English), light/dark themes, and options to share results. The interface is responsive and optimized for low power consumption and provides haptic feedback for key interactions.

The app covers a wide variety of categories and units: Length (meters, kilometers, miles, inches, yards, feet, centimeters), Mass/Weight (grams, kilograms, pounds, ounces, tons), Volume (liters, milliliters, US/UK gallons, cubic meters, fluid ounces), Temperature (Celsius, Fahrenheit, Kelvin, Rankine), Area (m², hectares, acres, ft², km²), Speed ​​(km/h, m/s, knots, mph), Time (seconds, minutes, hours, days, weeks, months, years), Angle (degrees, radians), Energy and Power (joules, watts, BTU, calories, kWh), Pressure (pascals, bar, psi, atm, mmHg), and Data/Information (bytes, KB, MB, GB, TB, PB). It is ideal for both everyday users and professionals who need fast and reliable conversions.

For currency conversions, the app uses real-time rates with local storage to work offline when necessary; it allows you to convert between any currency pair (e.g., USD ↔ EUR). Practical examples: if the rate were 1 USD = 0.92 EUR, then 10 USD → 9.20 EUR; and if 1 EUR = 1.09 USD, then 50 EUR → 54.50 USD.
