DIW — Group money sharing, simple and transparent

Suggested tagline: "Go out carefree, clear money."

Overview

DIW is an app that helps friend groups, colleagues, travel clubs, or roommates easily record and share common expenses. Instead of messy notes or mental calculations of "who owes whom," DIW automatically tracks debts and clearly shows how much each person needs to pay or receive.

The problem DIW solves

Every time you go out to eat, travel, or share a space, splitting the bill often creates awkwardness: the person who pays first has to remember each amount, others forget how much they owe, and in the end, someone ends up losing out. DIW makes this transparent, automatic, and removes the awkwardness of reminding each other.
