CartLock

CartLock is a mobile + browser extension app that adds a “cool-down” layer to online shopping. When you try to checkout, it can enforce a delay (e.g., 2 hours or 24 hours), require a quick reflection prompt, and show a simple “regret risk” score based on your past returns, late-night purchases, and category triggers you set. It also tracks price changes during the cool-down and alerts you if the item drops, so waiting feels like a win instead of friction. Users can whitelist essentials (groceries, meds) and set hard monthly caps by category. The goal isn’t to find deals—it’s to reduce wasteful spending and return hassles with minimal setup. Monetization: $4.99/month subscription, plus optional affiliate revenue when users choose alternative items after the cool-down.
