DuoSpend Budget

DuoSpend Budget answers one simple question: who owes what to whom? The app helps couples track the expenses of a shared project without turning it into a monthly budgeting app, a bank-connected tool, or a group expense tracker. Each project stays focused, with its own budget, expenses, and balance. DUOSPEND BUDGET IS: * built for 2 partners, not for groups; * organized by project: trip, wedding, moving, renovations, baby project; * centered on a balance that updates instantly between the two of you; * local-first, with no account, no ads, and no tracking; * able to share projects manually between two iPhones using DuoSpend project files; * an iPhone app available in French and English. FEATURES: * create and edit projects with a dedicated budget; * add, edit, and delete expenses in a few taps; * split each expense 50/50 or with a custom ratio; * see the updated balance instantly to know who should reimburse whom; * share a project using a DuoSpend project file; * import a new project or update an existing one from a received file; * open DuoSpend project files from iOS; * complete settings with light, dark, or system theme, purchase restore, data deletion, and an about section; * Home Screen widgets and PDF export with DuoSpend Pro. DUOSPEND PRO: * 1 free project to use DuoSpend Budget in real conditions; * DuoSpend Pro is a one-time €6.99 purchase that unlocks unlimited projects, widgets, and PDF export; * DuoSpend Pro supports Apple Family Sharing; * no subscription. PRIVACY: Your projects and expenses are stored locally on your iPhone. DuoSpend Budget does not collect personal data, does not use BeAbot servers, and works offline. When you choose to share a project, DuoSpend Budget creates a file that you decide to save or send using the services provided by iOS. Project sharing remains manual: DuoSpend Budget does not automatically sync projects between the two iPhones.
