Quiz Time! Understanding the App Explosion.

How many apps do you have on your mobile phone?

If you're like most modern consumers the number ranges anywhere from 11-20 (Pew Research), and the time you spend interacting with them is growing at record pace.

Globally, time spent in apps grew by a staggering 114 percent on Android phones from 2014 to 2016 according to App Annie Intelligence, with communication and social apps like WhatsApp Messenger and Facebook attracting the largest share of time spent. Time spent in media and video apps (like YouTube) has also grown by 212 percent over this period and is on the brink of overtaking games.

Even so, app retention remains a critical issue in this ecosystem with 75 percent of all app users churning within 90 days (Localytics). Despite this challenge, many brands are considering tapping into this competitive yet potentially lucrative market.

Knowing the factors that contribute to app downloads, engagement and revenue is a good place to start. Take this months' Quiz Time to test your app-savvy and see if your app idea has legs based on 2016 data from App Annie (answers at the bottom of the page).
