It’s too early to know, but J.C. Penney is looking at it this way: The retailer estimates that more than 50 percent of its 86 million customers are iPhone users, and so there's a good chance that many of those Apple devotees will try out the tech giant's latest device.
"We have to move fast, and this is a risky proposition. No one’s ever done this before," said Mike Rodgers, J.C. Penney's executive vice president for omnichannel.
Two J.C. Penney engineers worked at Apple's headquarters in Cupertino, Calif., for about three months to build the Apple Watch app. Because of the secrecy surrounding the project, Rodgers said he "had no idea" exactly what his staffers were developing until they returned to home base.
Rodgers imagines that the primary case for the Apple Watch app will be as a "shopping companion" to customers who are out and about at J.C. Penney stores. That's why one function will allow them to look for an out-of-stock item in a different color or size at the four J.C. Penney stores closest to their location. The app will even give them turn-by-turn directions to the store that has the item in stock.
And if you've saved an item in your online shopping basket while browsing on your desktop, smartphone or tablet, you can call up that list of items on the Apple Watch app to identify them easily in store.
The other core functions of the app seem geared toward online shoppers, such as a gift ideas feature that suggests items that cost between $25 and $100. At launch, J.C. Penney will build that list with items that are "trending" on its Web site, but in the future, they could curate it for a special occasion such as Father's Day or graduation. If you like one of the products, you can add it to a list of saved items and then easily purchase it from your phone, tablet or desktop later.
J.C. Penney's Apple Watch app can also quickly check the status of an online order to see where it is along its journey to your doorstep.
For now, that short list of functions is all that the Apple Watch app will allow shoppers to do. But J.C. Penney said that simplicity is deliberate, in part because no one quite knows how shoppers are going to use the device, and in part because the retailer had a tight timeline to build it.
The company expects to develop new iterations of the app as it hears from customers about how they are using the Apple Watch.
If J.C. Penney's app design is a preview of how the broader retail industry may use the Apple Watch, it seems that the playbook for these new devices will be a similar to their strategies for the phone.
With traditional smartphone apps, many retailers have found that shoppers do not use them when they're on the subway killing time or on the couch at home unwinding: They're using them inside the store to do price comparisons, read customer reviews or look for out-of-stock colors and sizes. And so when it comes to the Apple Watch, it appears J.C. Penney -- and probably other retailers -- will be looking to deliver even more immediacy and efficiency to that connection between physical shopping and online browsing.
"When someone's in the store shopping, the easier you can make it for them to get information about the shopping experience, the better it’s going to be," Rodgers said.
