How NagdiWay works
Rates you can check
Exchange rates come from central banks via Frankfurter, and every result shows the date the rate was published. An old rate is never shown as live.
Nothing hidden in the maths
Each calculator prints the formula it used and the assumptions behind it, so you can verify the number yourself.
