This would be a place in the app to see where your money is invested and other information.
Vanguard does this, showing which countries you’re invested in and the biggest companies in your portfolio, and your breakdown of equities and fixed income and industries. Example of this is attached.
For ETFs it might be hard to do something like this at Freetrade since you’d be looking up all their constituent parts. But I think Freetrade could make something look nice and help see how diversified your holdings are.
