Currently, the iOS widget shows the total return od the account, in absolute numbers, and when you expand the widget, it shows the returns of the individual stocks, also in absolute numbers.
My feature suggestion is:
1 - Show percentages instead of absolute numbers. (also good for privacy)
2 - At least have the option to choose to see the Pies instead of individual stocks.
I used a lot of widgets, so showing the pies will be very helpful in skipping to open the app every time just to check the pies performance.
