AppsFlyer says retaining users is still a challenge for app marketers

Retaining app users over time continues to be a major challenge for app marketers, according to a new report from mobile app measurement and marketing platform AppsFlyer.

The report said that only 10 percent to 12 percent of users remain active seven days after downloading an app, and a mere 4 percent to 5 percent are still active after 30 days.
