Not a direct competitor of Monzo, as it’s not a bank and doesn’t appear to have any aspirations to become one, but Pariti have some pretty nice features around forecasting ones financial activity across multiple accounts, both debit, credit and savings and is able to predict when a person will be free of debt based upon spending and savings habits. I know cash flow forecasting is on the roadmap, under the better budgeting feature I think I’m right in saying.
As Monzo is building a bank to help us better manage our finances, maybe they should become friends, or at least learn from what they’re doing as it would be handy to see my expected income and expenses in one neat app
