Email SupportWhy does the currency rate change?
It's fetched live from a public exchange-rate service each time you open the Currency tab, so it reflects current market rates rather than a fixed number. You can also refresh it manually or type in your own rate.
Does the app work offline?
Distance, weight, and temperature conversions work fully offline. Currency conversion needs an internet connection to fetch the live rate; without one, it falls back to the last known rate.
