Redesigning the Shared Expenses Experience for Groups and Friends

Splitting expenses with friends, roommates, or partners is a frequent but frustrating task. Whether it’s tracking who paid for dinner, splitting rent, or settling after a trip, users often turn to spreadsheets or screenshots. Existing tools are rigid or overly formal. There’s room for a more social, fluid, and low-friction approach to shared finance.

Most shared expense tools feel transactional, with little flexibility, visibility, or trust-building features. Users need a more intuitive way to split, track, and settle shared costs—without confusion or awkward reminders. The challenge is to design a shared expenses feature that’s as clear as it is social.

Friction in tracking who owes what, especially across time

Tension or confusion when sending reminders or settling

Lost context around payments ("Was this for groceries or the trip?")

Friends sharing everyday or travel expenses

Couples managing joint spending without a shared account

Roommates splitting rent, utilities, and groceries
