Good app for my needs

First is to developers, please make taps more obvious. I often dont know if my numbers or additions have registered. The tap is too subtle, but it looks clean. I often deal internationally for transactions so this app is very helpful out of the few I have tried out. Not having to press equal is nice. The design is nice. The Ui is pretty good. Not many complaints but wish there was a way to calculate without losing the current exchange rates
