CouponLedger

CouponLedger is a mobile + browser-extension app that automatically captures, organizes, and applies legitimate savings across online and in-store shopping without turning into spammy “deal noise.” Users link email and optionally loyalty accounts; the app extracts real offers (promo codes, targeted coupons, rebates, gift-card promos), tracks expiration dates, and surfaces the best eligible savings at checkout. For in-store, it generates a clean barcode/QR “coupon wallet” and reminders when you’re near a participating retailer. The app also keeps a simple “savings ledger” showing what worked, what failed, and which stores consistently waste your time with invalid codes. This is not a magical price predictor; it’s a reliability-first tool that reduces the friction and embarrassment of coupons that don’t scan or codes that don’t apply. Monetization is a mix of affiliate revenue (when it genuinely saves money) plus a low-cost premium tier for advanced tracking and family sharing.
