What do you want to be added or improved?

Let's say we're trading USD-EUR in a bank app.

The bank app tells you, you're spending 1000 USD and getting 918 EUR (it's 921.35 by Google).

It's annoying to do the calculation to get the bank exchange rate.

It will be good if I can input 1000 USD and get 918 EUR and leave the exchange rate calculated.

Why do you need it?

How do you imagine it?
