As is always the case, the iPhone 7 and iPhone 7 Plus went out of stock at Apple Stores across the world, hours after being launched last week. Due to the high demand, some iPhone Upgrade Program customers were also unable to place an order for the model they desired because of the limited stock availability.

Fortunately, there’s now a new website called iStockNow that helps customers find out what’s in stock at their local Apple Store as well as worldwide stores.

The site uses Google Maps to display the availability of iPhone 7 and iPhone 7 Plus stock at Apple Stores across the globe, based on Apple’s reservation system backend. You can filter stocks by iPhone model, carrier, color and storage space as well as search stores by country, city or ZIP code.

Apple Stores with available stock based on your search criteria are marked as green, whereas those that are out of stock have a red marker. If you click on any of the markers, the site displays a table of iPhone stocks that are available based on model, color, carrier and storage size. You can click on an available stock to be taken directly to Apple’s website to place an order for that particular model.

iStockNow updates the stock availability of all stores in real-time, so you can get a live information of which iPhone models are available at your local Apple Store at a particular time.

After preorders for the iPhone 7 and iPhone 7 Plus launched last week, most Apple Stores went out of stock within a few hours due to the high demand and limited stock availability. However, iPhone 7 and iPhone 7 Plus availability seem to have improved in certain parts of the US based on the information on iStockNow, but the Jet Black color is still out of stock in most stores.
