With Revolut having a per month limit that can be attached to the card, and auto tagging of transactions, would it be possible to implement a transaction type budget limit?
Ie: I only allow £20 a week to be spent at coffee places (starbucks, costa etc), so once this limit is being approached I get updates on my phone to notify me and if i try to spend over this limit the transaction is refused?
Also I think the flexibility to set limits on a per week basis would be extremely helpful too
