Since Apple’s iPhone 7 is hard to come by, some are undoubtedly looking for tools to help them find out what’s in stock. And one site does that well.

A site called iStockNow offers a single spot for users to find an iPhone 7 from any carrier, in any color, in any size, from Apple AAPL Stores across the world. The site has a live-update feature so users can see in real time what’s available on a map featuring all the Apple Store retail locations. It’s updated on an ongoing basis, so users can see at that particular time whether their local Apple Store has an iPhone 7 or not.

The site, which has been around for years, focuses each year on the latest Apple smartphone. This time around, it’s the wildly popular iPhone 7. The smartphone, which was unveiled earlier this month, comes with a slightly updated design, a dramatically improved processor, and a better camera. The smartphone, however, doesn’t come with a headphone jack, which made some question just how popular the iPhone 7 would be.

After pre-orders kicked off and pushed back shipments to as late as November just hours after they began, however, some of that concern was put to rest. Just before the iPhone 7 officially went on sale on Friday, Apple announced that the bigger iPhone 7 Plus wouldn’t be available in-store on launch day due to overwhelming demand. The iPhone 7 has had sporadic availability, depending on where consumers live.

As of this writing, iStockNow, which was earlier reported on by gadget site BGR, is actually showing relatively widespread iPhone 7 availability across the U.S. From New York City to California, most Apple Stores appear to have iPhone 7 models available. Further inspection, however, reveals that only some stores have iPhone 7 Plus models, while most have just about any iPhone 7 variation customers could want. That’s keeping with Apple’s earlier reports that iPhone 7 Plus will be hard to come by for at least the foreseeable future.

Also worth noting from iStockNow’s data is that the jet black iPhone 7 is a no-show in any of the stores that Fortune examined on Tuesday. It’s likely that version won’t be available for some time, since it was the most sought-after during pre-orders and on launch day.

For those who don’t want to use iStockNow, Apple.com also features the ability for users to check what’s in stock. But at least in my experience, iStockNow is a bit easier to use when there are multiple stores around a location that customers can go check out. It doesn’t, however, show stock from non-Apple stores.
