iPhone

Split expenses, read receipts line by line, settle debts in one tap. Friends only need a link, not the app. Tandu splits group expenses for roommates, trips, couples and events, and shows the working behind every number. ONE LINK, EVERYONE'S IN You send a link. Friends without the app open it in the browser, pick "That's me", see where things stand, add expenses and choose their items from the receipt. No account, no email. RECEIPTS, NOT HEARSAY Photograph a receipt and Tandu reads the line items. Everyone taps their own items and gets their share. Every number comes with its working, so nobody has to ask how it was calculated. If the items don't add up to the receipt total, Tandu says so. PAY WITHOUT THE DETOUR Every debt has a pay button: a GiroCode (euro, with an IBAN on file) for any German banking app, a PayPal link with the amount, or a Wero link, if the recipient has entered them. You pay where you already pay. FREE, NO LIMITS Unlimited groups, members and expenses. All split modes, line items, currencies, PDF and CSV export, the basic statistics view, on-device receipt reading, sync and backup. No ads, no tracking. TANDU PRO If you want more, there is Pro: cloud receipt scans on a fair-use basis (3 a month are free), a Live Activity for "Everyone picks their own", statistics with periods and comparison, recurring expenses, widget variants, alternate app icons and large receipt storage. Pro comes as a monthly subscription, a yearly subscription, a trip pass for one group (30 days, does not renew) or a one-time lifetime purchase. Subscriptions renew automatically until you cancel in your Apple ID settings. What is free stays free. Tandu never holds money. It calculates, explains and shows who owes whom how much.
