Consumers spend longer in apps than mobile websites, with app sessions an average of three to four times longer than sessions spent on mobile websites, according to data from the Adobe Digital Index.

Smartphone apps are used more than twice as often as mobile websites while combined monthly app usage is 100 minutes per user more for mobile apps than mobile web visits.

The data also showed that tablet users spend longer in apps than smartphone users. Tablet users spend around 24 minutes in an app while smartphone user sessions are an average length of 13 minutes.

Android apps are used 40 per cent more often each month than their iOS counterparts, but users spend twice as much time in iOS apps. This suggests Android users have a greater tendency to download apps and discard them after using them once.

The Adobe Digital Index measures engagement on apps and web for more than 600 brands.
