Lumi AI - Voice Expense Tracker
Lumi is a voice-first expense tracker and AI budgeting app for iPhone, available on the App Store. It lets users log an expense by simply saying something like "coffee, five euros" and the app automatically records the amount, merchant, and category using AI. Instead of requiring bank account logins, Lumi relies on Apple Pay auto-import, receipt scanning, and manual voice input to keep spending data private and stored on-device. Beyond logging, Lumi offers an AI spending forecast that projects month-end balance based on recent spending history, category budgets with live progress, multi-currency support with real-time conversion, and Family Sharing for partner budgeting. It is designed to reduce the friction of expense tracking: users can activate voice capture via Back Tap, scan paper or screen receipts, and confirm auto-suggested categories within a few taps. The product emphasizes privacy, with no bank connection and offline functionality. It is free to start with premium plans for additional features. Lumi is positioned as an alternative to manual budgeting apps and bank-connected trackers, aimed at individuals and families who want a fast, private way to manage personal finances.
