Record demand for online grocery shopping amid the COVID-19 pandemic has sent the apps for grocery pickup and delivery services up the charts. Walmart Grocery, as a result, has now hit an all-time high in downloads — grabbing the No. 1 ranking position across all Shopping apps in the U.S. on April 5, 2020, and surpassing Amazon by 20%, according to a new analysis from app intelligence firm App Annie.The Walmart Grocery application retained that No. 1 position for at least two days, the firm said, citing data from both the Google Play store and the Apple App Store, combined. While App Annie’s data was calculated on April 7, 2020, Walmart Grocery is still No. 1 on Google Play as of today, April 9. It’s also now No. 2 on the App Store.
