Before you ask...
What is Stalk?
An app that watches prices for you. Save a product, and Stalk tracks it across stores, predicts when it's likely to drop, and tells you when and where to buy it for less.
How does Stalk know a sale is coming?
It looks at an item's price history and how similar products have moved around sales and seasons, then gives you an estimate with a confidence score. Predictions are estimates, not guarantees, so you'll always see the current best price too.
Do I need all three apps?
No. Use whichever fits. One account syncs your watchlist across the Chrome extension, the web app and iOS, so you can save on one and get alerts on another.
Does Stalk buy things for me?
No. Stalk tells you the price and where to find it. You decide whether to buy, and you check out with the store as normal.
Which stores will it work with?
The launch store list goes to the waitlist first. Stores shown on this page are examples.
What will it cost?
Pricing will be announced before launch. Joining the waitlist is free.
When can I use it?
Waitlist members get access first. We'll email you as soon as your spot opens.
