Your home screen shows everyone's net balance instantly — green if you're owed, red if you owe. No spreadsheets, no mental math.

Frequently asked questions
What is the best free roommate bill splitter?
BillSpilt is a free roommate bill splitter built specifically for shared households: it tracks who paid for what, shows everyone's balance instantly, and settles up in the fewest payments. Unlike many bill splitters, every feature — recurring bills, reminders, receipts, multiple admins — is free forever, with no paywall and no credit card.
Is BillSpilt really free?
Yes — free forever, no premium tiers and no credit card. The app is supported by ads, which lets us keep every feature free for roommates.
Does BillSpilt handle the actual payments?
No. BillSpilt calculates who owes what and links you straight to Venmo or Cash App, but the money moves directly between you and your roommates — we never hold or process funds.
How does the settle-up work?
Instead of everyone paying everyone, BillSpilt nets all the debts and finds the fewest payments that clear them — so four roommates might settle with just two or three transfers.
Can I use it on my phone like an app?
Yes. BillSpilt is a Progressive Web App — add it to your home screen and it runs full-screen and offline, just like a native app, with nothing to install from an app store.
How do we split unevenly?
Every expense supports three split types: evenly, exact dollar amounts, or by percentage — and you choose exactly who's included.
