Multi-currency expense tracking
A trip through five countries means five sets of prices and five sets of notes in your pocket. Tasca records the local amount and the converted amount for every expense, so the total holds up afterwards.
What you paid
The original amount and currency, exactly as it appeared on the terminal.
What it cost you
The converted amount in your home currency, using the rate that applied that day.
Which rate
The rate itself and its date, stored on the expense so a report you run in December still reflects August.
The keypad already knows where you are
You set a home currency when you start a trip, and Tasca works out a spending currency from the country. Open the keypad in Tokyo and it is on yen. Change the country to Korea and it moves to won.
The two stay independent. Paying in US dollars in Cambodia, or euros in a country that does not use them, is common, so Tasca suggests a match rather than changing the entry for you.
Rates you can point at
Conversion uses official central bank rates, aggregated by frankfurter.dev from more than 80 central banks. These are published figures, so the number in your report can be checked against a public source.
Rates are cached on your device and refreshed in the background. If the app cannot reach the network, conversion keeps working from the last rates it has, and anything using an old rate is marked as stale rather than presented as current.
- About 160 currencies with automatic daily rates
- Any currency at all if you enter the rate yourself
- A rate you set by hand is respected and never overwritten
- Each expense keeps the rate and rate date it was saved with
Cash, cards and the gap between them
Your bank will not give you the mid-market rate. It will give you that rate plus a margin, and possibly a fixed fee on top. Tasca lets you handle that in whichever way matches how you travel: log the card charge as it appears on your statement and set a custom rate, or log the local price and accept a small difference for the sake of speed.
For cash, log any withdrawal fee your bank charged under fees, then log each purchase at its local price. That keeps the local prices comparable and puts the fee where it belongs.
Common questions
Which currencies can Tasca convert automatically?
About 160, drawn from official central bank rates. That covers the majors and also the ones budget travel runs on: Vietnamese dong, Cambodian riel, Lao kip, Uzbek som, Georgian lari, Moroccan dirham, Sri Lankan rupee and so on. Anything outside that can be logged with a rate you enter yourself.
What rate does Tasca use for an expense I add later?
The rate for the date of the expense, not the date you typed it in. Adding Tuesday's dinner on Friday still converts at Tuesday's rate.
Can I change my home currency mid trip?
Yes, in trip settings. Existing expenses keep the original amount they were logged in, so changing the home currency re-reports rather than rewrites your history.
