SplitBook

Now faster: vendor suggestions speed up entry. Split household expenses, settle up, and sync free via iCloud. No accounts, no subscriptions.

Track shared household expenses, split costs fairly, and settle up — without spreadsheets, group chats, or yet another account.

SplitBook is built for couples, families, and roommates who want a simple running ledger of who paid what and who owes whom. Everything syncs through your private iCloud account, so there are no servers, no logins, and no third-party trackers between you and your household.

WHAT YOU CAN DO

• Log expenses in seconds — vendor, amount, category, who paid • Split four ways: – Equally among everyone in the household – For selected members only – By exact amount when shares aren't even – None, if it's only the payer's expense • Built-in math (+, −, ×, ÷) for combining items at checkout • Record payments between household members and link them to specific expenses so balances always reflect reality • See net balances ("Ellen owes you $87.50") with the math done for you across every transaction • Visualize spending by category and timeframe with a clean donut chart • Search across every expense and payment instantly

BUILT FOR HOUSEHOLDS

Invite household members with one link — no logins, no email list, no third-party account to sign up for. iCloud handles the identity. Everyone's view of the shared ledger stays in sync, even offline.

YOUR DATA IS YOURS

• Everything stored on your device and synced through your personal iCloud account • No analytics. No telemetry. No third-party servers. • Export to a backup file any time. Restore any time.

PRIVACY

SplitBook does not collect any data about you. We don't have servers, we don't have accounts, and we don't have your financial information. Your expenses stay between you and your household.
