Buddies/Housemates debts settling up

If saving pots were available, you could set one up for each user / bill to make payments from & keep track of who owes what that way.

Saving pots for individual users have been discussed here -

& here -

they’re on the roadmap.

This is also the sort of feature that a 3rd party developer could develop. Splittable could connect to Monzo’s API & feed in transaction data to avoid manual data entry.
