CHICAGO: American smartphone owners use their favourite app for 42% of all the time they spend accessing apps, a new report into iPhone and Android behaviour has revealed.

According to the US Mobile App Report from comScore, the internet technology research firm, app usage now accounts for over half (52%) of all digital time in the US, but only a few well-known app brands dominate overall usage.

As reported by MediaPost, six big tech brands – Facebook, Google, Apple, Yahoo, Amazon and eBay – account for nine of the top 10 most-used apps, 16 of the top 25, and 24 of the top 50, with Facebook leading for both the largest base of users and the most time spent.

Nearly three-quarters of the time US smartphone users spend with apps is concentrated on just four apps, the report also found, while more than half (57%) access apps every day.

While Facebook and some other brands remain dominant, smaller apps can still achieve success, said Adam Lella, a marketing insights analyst at comScore.

"It certainly means there might be some challenges for smaller players on this medium, but success is also very possible," he said in comments reported by AdExchanger.

He explained: "We have seen some standalone apps achieve huge audiences on mobile, for example SnapChat and Pandora, while others have found ways to monetise through non-advertising business models that don't require competing with the larger companies on audience size, like Uber and certain gaming apps."

The report also noted some behavioural and demographic differences between iPhone and Android users with the former being younger and wealthier.

The median iPhone user earns $85,000 a year compared to $61,000 for Android users, and 43% of iPhone users are aged 18 to 34 versus 39% of Android users.

iPhone users are more likely to use apps to consume media, such as general news and social networks, while Android users focus more on apps for search and email, which comScore attributed to the strong presence of Google Search and Gmail on the platform.
