Pricewatch

Track prices on any website. Get notified when they drop. Never overpay again.

PriceWatch monitors product prices across any e-commerce site and alerts you the moment a price falls below your target — even when you're not browsing.

What it does

- Works on any store — Amazon, eBay, Best Buy, Walmart, local e-commerce sites, and more
- Checks prices automatically in the background at an interval you control
- Sends a desktop notification (and optional mobile push) when a price drops below your target
- Tracks stock status — shows in-stock / out-of-stock per store, suppresses false alerts when items are unavailable, and notifies you the moment something comes back in stock
- Tracks the same product across multiple stores simultaneously — always shows the lowest in-stock price
- Keeps a full price history with a sparkline chart so you can see price trends over time
