Did you know: The average Android app loses 77% of its users in just 72 hours!
App users are impatient! Also, sad frog is sad.
the average app loses 90% of its daily mobile users within 30 days of the initial install.
Chen’s data also indicates another interesting tendency. The Retention rates among Google Play's top 100 apps show a drop off within the first 90 days after launch, with the speed of that drop off mirroring that of the average apps analyzed prior to that. Users actually find the top apps appealing in the first seven days, return to them repeatedly during that period, and then use them less over the next 90 days.In other words, app developers must make sure that their creation's success is largely dependenton how a user interacts with it from the first minute post-install. Chen concludes that top apps retain users because they either have a 'wow' factor to them, or they integrate with mobile life to such an extent that they become essential, and not having access to them is unthinkable for users.
