iPhone X support? iPad portrait mode?

Dk Danes

Very fine currency converter. Being able to choose sources is actually a great feature. My only wish is that there's a portrait mode as my finance apps work on portrait and its a hassle rotating the iPad everytime. iPhone X would be welcome.

Perfect UI for currency calculations


I use this time long time already.
It looks intuitive and clean. All needed sources of exchange rates available in settings.

Developer support is great and responding very fast, they updating this app often.

This is the only app I use for fast exchange rate calculations.
