Amazon led the pack even though it was working off a substantially larger user base, having received more than 35.4 million Apple iOS downloads since January 2012 — the most of any retailer, Sensor Tower said.
Wish, an app that helps shoppers find discounts on unbranded items, ranked second in terms of iOS downloads on Black Friday, with 62,000. Other retailers finishing in the top 10 were Wal-Mart, eBay and Cartwheel by Target.
Separately, SimilarWeb — which measures app use on Android devices — said Best Buy and Staples led the pack in terms of active app use in the six days ended Cyber Monday.
Overall, major retailers have continued to invest in mobile app technologies, despite consumers' reluctance to adopt them. That's because the payoff for converting a shopper can be substantial.
According to a recent report by Forrester Research, 41 percent of U.S. smartphone users visited Amazon's mobile website during the second quarter — twice as many visitors as its mobile app received. But mobile app users visit the app 4.9 days per month, compared to 3.3 days per month for mobile site visitors.
What's more, shoppers who use a retailer's mobile app have already entered their preferred payment method, making it easier for them to complete transactions on the tiny devices.
