Would you like to see the value of your accounts in your chosen native currency? No problem.
From the settings page, toggle the 'Show currency conversions' slider to the right.
On the home screen, you will now see the value of your non-native currency, as valued in your native currency. You will see this under your non-native currency balance at the top of your home screen.
For example, with your native currency set to GBP, you would now see the value of your bitcoin account in bitcoin as normal on your home screen. Underneath this, you would see the current value of this balance displayed in your native currency, GBP.
