App usage doesn’t differ wildly between genders: Women spend 3.2 minutes per session compared with 3.0 minutes for men. But age does play a role. Millennials, for example, spend the least amount of time per session (2.6 minutes). By comparison, Gen Xers spend 3.4 minutes, baby boomers spend 4.3 minutes and those 75 and older spend just shy of 5 minutes.
Verto Analytics' findings are in line with a February 2018 study from Salesforce Commerce Cloud (formerly Demandware) that measured retail ecommerce visits of more than 500 million shoppers worldwide by device. In Q4 2017, mobile—though not apps specifically—had the shortest average visit duration (3.85 minutes) compared with tablets or computers.
Meanwhile, a November 2017 survey of US smartphone users from Button and App Annie showed shopping app usage decreases with age. Millennial respondents prefer mobile shopping via apps (62%) as opposed to mobile web, while 44% of boomers prefer shopping by app. Many shopping apps offer the ability to save logins, personal details and payment info, which speeds up the buying process.
