Good app with potential to be great
Having a widget that displays historical graph instead of just numbers is great. It does need a bit more customization though. Theres no way to set the time frame of the graph and the exchqnge rate is always 100 instead of the normal 1. There needs to be a way to alert users when exchange rate went above + below certain range. Either a preset exchange rate number or offset from previous date would be great. It would basically alert users of large swings in the currency. The frequency of the app updating the rates needs to be displayed prominently. Indeally, within the app it should update every 1 minute like XE.
