This app will be released when the public API is released early next year after current accounts.
Here is a list of current features in the app:
There's a lot more to come. I welcome suggestions.
Spend per transaction type, e,g. chip and pin, atm, contactless
Spend per currency, for frequent travellers.
A graph of returns/refunds separate from spending.
And spending periods not just monthly or weekly but options of 2 weekly and 4 weekly too
