IOU - Shared Expenses

Track shared expenses with your household, roommates, or travel group — without an account, a cloud, or a subscription. Add an expense in seconds. Snap a receipt and let on-device OCR fill in the amount. Assign a category, mark who paid, and IOU keeps a running tally of who owes whom. When it's time to settle up, close the period and IOU works out the minimum set of payments to balance everyone out. HOW SYNC WORKS IOU never sends your data to a company server. Devices pair with a QR code and sync directly — over your local Wi-Fi, or across the internet via encrypted WebRTC. Public relays are used only for the initial rendezvous; your expenses stay end-to-end encrypted with a secret that only your paired devices know. FEATURES • Categorized expenses with custom icons • Receipt photos with on-device OCR • Per-member avatars • Automatic balance calculation and settle-up suggestions • Historical periods you can revisit • Local backup and restore • Light, dark, and dynamic color themes • Full English and Italian localization FREE AND PRO IOU is free forever for a single group. Pro (one-time purchase) unlocks unlimited groups from a single install — great if you split expenses with your household AND a separate circle of friends. PRIVACY No account. No advertising. No analytics. All data lives on your devices, encrypted in transit and accessible only to people you've paired with.
