Questions
How do I add costs in different currencies? Write each with its currency code, for example “120 usd”. Ratio converts every line into the currency of the first one when you use sum.
Do I need internet abroad? No. Ratio works offline with the last downloaded rates, so a budget on a plane or without roaming still adds up.
Can I split the total between friends? Yes: divide the sum by the number of people, for example “prev / 4”.
