Shared expenses, simplified.
SplitBook makes it easy for households to track shared expenses, split costs fairly, and settle up—all synced in real time across everyone’s devices via iCloud. No accounts to create, no subscriptions. Just add your household members, start logging expenses, and let SplitBook handle the math.
Split expenses equally among everyone, select specific members, or assign the full amount to one person. You decide who owes what.
Expenses, payments, and members stay in sync across all household devices automatically. Works offline and catches up when you reconnect.
See who owes whom, recent transactions, and spending by category—all on one screen. Know exactly where your household stands.
Record payments and link them to specific expenses. Mark debts as partially or fully settled with a clear audit trail.
Invite family members with a single link. Everyone gets their own view of the shared expenses, synced through iCloud.
Organize expenses your way. Create custom categories with icons, reorder them, or remove ones you don’t need.
Get notified when a household member adds an expense or payment, or when someone new joins. Stay in the loop without opening the app.
Export your household data to a file and restore it anytime. Your data stays on your devices—never on a third-party server.
SplitBook stores all data locally on your device and syncs exclusively through your personal iCloud account. There are no third-party servers, no analytics, and no accounts to create. Your financial data stays between you and your household.
