CartClock

CartClock is a mobile + web app that tracks flash-sale items you actually care about and tells you when to act—without endless scrolling. Users paste product links (or forward email promos), set a target price and urgency level, and CartClock monitors price drops, stock status, and sale end-times across supported retailers. It sends “last-call” alerts when inventory is collapsing or the timer is about to expire, and it can auto-build a ready-to-checkout cart list so you can purchase fast. The app focuses on a small set of high-signal sources (major retailers and brand sites) rather than trying to cover the entire internet poorly. It also includes a “Deal Confidence” score that flags fake markups and recycled “sales” by comparing recent price history. Monetization is subscription plus optional affiliate revenue; the free tier is intentionally limited to avoid high scraping costs.
