Build a Splitwise-style group expense tracker. Multiple groups (Roommates, Weekend Trip, Office Lunch). Each group has members, each expense has a payer, an amount, and a list of people the bill splits between (default: everyone). Balance summary per member (positive = owed, negative = owes). Settle-up view shows the minimum set of transfers that zeros everyone out.

Create a roommates bill-splitting app. Rent, utilities, groceries, and shared subscriptions in one place. Each expense tagged with a category. Monthly summary of total spend per category and who's behind on their share. CSV export of the month so it can be archived after settle-up.

Design a trip expense splitter for a group vacation. Currency selector per expense (USD / EUR / GBP) with a static conversion rate table the user maintains. Per-day spend breakdown. 'Settle up' button generates the smallest list of payments needed to balance everyone out at the end of the trip.

Build an office lunch expense splitter. Recurring weekly lunch group, rotate-the-payer-by-week tracking, automatic monthly settle-up reminder, and a leaderboard of who has paid most this quarter. Print-friendly settle-up sheet for the office whiteboard.

Frequently asked questions

How is this different from Splitwise / Tricount?
Splitwise / Tricount are SaaS apps with a free tier and paywalled features. FloopFloop generates an app you fully own — refine the splitting rules, the categories, the settle-up algorithm, anything. No row caps, no ads, your data lives in your own per-project database. Start from the template and iterate by chat.
How does the settle-up math work?
Each expense credits the payer the full amount and debits each splitter their share (with the last splitter absorbing rounding pennies so cents tie out exactly). Per-member net balance = sum of credits minus sum of debits. The settle-up view uses a greedy algorithm: largest creditor receives from largest debtor until both flatten, repeat. Produces close to the minimum number of transfers for typical group spending — refine with 'use a flow-network solver for proven-optimal transfers' if you need it.
Can splits be uneven?
The default template ships with even-split (everyone in the group pays the same share). Refine with 'add a percent-split mode where each splitter has a weight (Alice 40%, Bob 30%, Carol 30%)' for proportional splits, or 'add an exact-amounts mode where the splitter enters dollar amounts that must sum to the total' for itemized restaurant-style splits.
Where is my data stored?
The default template uses browser localStorage so the app works instantly with no signup. Refine with 'add a Postgres backend so groups sync across devices' to move to server storage — the codegen adds the schema, the API routes, and the sync logic in one round. The codegen scanner blocks every external database (Supabase, Firebase, MongoDB) so the data stays on your own per-tenant Postgres schema.
Can multiple people edit the same group from different devices?
Not in the localStorage-only default — that's per-device. For shared editing refine with 'add a per-group share URL that anyone with the link can read; add a per-group passcode that anyone with it can write'. The codegen generates the route, the access check, and the conflict-resolution logic (last-write-wins is fine for low-contention group expense editing).
Does it handle multiple currencies?
The default template treats every amount as a single currency (dollar-style formatting, integer cents internally to avoid floating-point drift). Refine with 'add a currency column per expense + a user-maintained fx-rates table so each expense displays in its native currency and the settle-up converts to the group's base currency' for a trip-with-international-stops use case.
Can I generate a settle-up email or Venmo link?
Refine with 'add a Venmo deep link (venmo://paycharge?txn=pay&recipients=USERNAME&amount=AMOUNT&note=NOTE) on every settle-up row so tapping it opens the Venmo app pre-filled'. The codegen wires the deep link and the share intent. Email refining works the same way — 'email each member the settle-up sheet via Resend' adds the route and the template.
