Can I log an expense in a different currency?

Yes. Log it in the currency you actually paid in.

1. On Add expense, tap the currency next to the amount and pick the one you paid in, for example SGD.
2. Enter the amount in that currency.
3. NEXO shows what it comes to in your home currency, using today's exchange rate.

The rate is saved with the record. Your totals won't change later when exchange rates move.

Using your own rate: if your bank charged a different rate, tap the converted amount and type the real figure. NEXO marks it custom rate. Tap Reset to live rate to undo.

"No exchange rate for…" NEXO needs an internet connection to fetch rates. See Why does NEXO say an exchange rate isn't available?
