Online prices don't sit still. The jacket you bookmarked on Monday is 20% off on Thursday and back to full price by the weekend. Retailers reprice constantly, sometimes several times a week, and unless you happen to look at exactly the right moment, you pay whatever the price happens to be when you run out of patience.

Most of us cope with some version of the same ritual: a graveyard of open tabs, a wishlist we check when we remember to, and a vague feeling that we probably overpaid anyway. The timing problem is real, but solving it by hand is a part-time job nobody wants.

dipd exists to make timing automatic.

One tracker for the whole internet

dipd is a price tracker that works on any store. Not a catalog of supported shops, not one retailer's app. If a store has a public product page with a price on it, you can track it. Paste the link, and dipd starts watching.

That one idea changes how the whole thing feels. Your tracked products live in a single dashboard whether they come from a giant marketplace, a fashion house, or a tiny specialist shop you found at 1 a.m.:

dipd dashboard showing products tracked across Target, Walmart, Gucci, Amazon, Newegg and more, several with price-drop badges — One dashboard for everything you track, whatever the store.

From there, the loop is simple:

Paste a product link into the web app.
dipd checks the price on a schedule: daily by default, up to hourly on premium.
You get an email the moment it dips. Open the link, buy at the lower price, move on with your day.

Want to poke around before signing up? The live demo is this exact dashboard filled with seeded products. No account needed, and it resets on reload, so click anything.

Price history turns "sale" into a fact

A discount badge on a store page tells you what the retailer wants you to feel. A price history chart tells you what actually happened. Every product you track in dipd builds one automatically, with lowest, highest, average, and every dip along the way:

When today's price is genuinely the lowest you've seen, buying stops being a leap of faith. When it isn't, you wait, and dipd keeps watching so you don't have to.

Where you can use it

Web app: your dashboard for everything you track, with history charts and alert settings.
Chrome extension (coming soon): track the product page you're on in one click.
iOS app (live on the App Store): track and check prices from your phone, and add products straight from the share sheet.
Android app (coming soon): the same on Android.

They'll all share one account, so a product you track in one place shows up in the others a second later.

What it costs

dipd is free: track products, get daily checks and email alerts without paying anything or entering a card. A premium tier adds hourly checks for the moments when a price war is actually on. Start free, upgrade only if you find yourself wanting faster refreshes.

What's coming on this blog

We'll keep this blog practical: what we learn from watching thousands of prices move, and honest guides on timing purchases: when sales are real, and when they're theater. We've started with a look at America's largest retailers and what their prices do. If that sounds useful, add a product or two and see for yourself below.
