Shared expenses, just for two.
Need a hand or have an idea? Email support@splitduo.app and we'll get back to you. You can also send feedback from inside the app: Settings → Submit feedback.
How do I get started?
Create an account, then create a household and share the invite code with the one other person you split with. Prefer to look first? Tap "Just looking? Explore the demo" on the sign-in screen to try the whole app with sample data — no account needed.
How do I split an expense that isn't 50/50?
On the Add screen, drag the split slider to any share, or tap All me / All them. Split Duo does the math to the cent. You can set a different default split in Settings.
How does receipt itemizing work?
Tap Itemize, take or choose a photo of a receipt, and Split Duo reads the line items so you can assign each one to you, your partner, or split. A limited number of scans are included; heavy users can add their own AI provider key.
How do we settle up?
Open Settle to see who owes who. You can send a Venmo request with a pre-filled note, then press and hold Mark settled to reset the balance to zero and log it. Settle-ups can be undone.
What is Split Duo Pro?
Pro is an optional one-time purchase (no subscription) that unlocks extras like your own AI key for unlimited receipt scanning, recurring expenses, CSV export, and profile photos. Already bought it on another device? Tap Restore purchase on the Pro screen.
Is my data private?
Your expenses and receipts are visible only to the two members of your household. We don't show ads or sell your data. See the Privacy Policy for the full details.
How do I delete my account?
In the app, go to Settings and use Delete account, or email support@splitduo.app and we'll take care of it.
