The number of ads is obnoxious – Currency Foreign Exchange Rate Review

The way I tried to use it was to read prices in a guidebook then switch. About 70% of the time a full-screen something displayed. Some were just screens. Some had sound. Once a mini-game tried to load. However, the ap does work if you can stand the barrage of ads.
