Split Duo

Split Duo is the simplest way for two people to share expenses and stay even. No group chats, no spreadsheets, no math — just one shared balance that's always up to date. Built for exactly two: couples, roommates, partners, siblings — anyone who splits life's costs with one other person. WHY SPLIT DUO • One clear balance. Open the app and instantly see who owes who, and how much. • Split it your way. Go 50/50 by default, or drag the slider to any share — Split Duo does the math to the cent. • Snap a receipt. Point your camera at a receipt and AI itemizes it line by line, so you can assign each item to you, them, or split. Reading one costs a credit. • Email one in. Forward a receipt email to your household's private address and it turns up on your balance with the merchant, total and date filled in — for you to check, never added on its own. Also costs a credit. • Settle up in a tap. Request what you're owed on Venmo with a pre-filled note, then mark it paid — partial or full, and always undoable. • See where it goes. Monthly totals broken down by category, plus a full history of every expense and settle-up. • Works without a signal. Add an expense with no connection and it counts in your balance straight away, then uploads itself when you're back on. • Make it yours. Attach receipt photos, add your own categories, and put a face to each name — all free. INTELLIGENCE CREDITS Having AI read a receipt costs one credit, whether you photograph it or email it in. Every household starts with 10, shared between you. Run out and you can buy 50 more for $2.99 or 200 for $9.99 — never a subscription, and they don't expire. Adding an expense by hand is always free. DESIGNED FOR TWO Most split apps make you build a "group" just for two people. Split Duo is made for the two of you from the very first tap — cleaner, faster, and easier to keep even.
