Many of us have one or two apps that qualify as "hidden gems."

They're the apps that aren't exactly at the top of the App Store, but we love and use them often. Maybe we heard about them from friends or discovered them through trial and error - either way, they're the apps we tend to believe are our own little secret.

It turns out, 21% of people say they have an app on their phone they consider a "hidden gem," according to comScore's "2017 US Mobile App Report," which gathers data about smartphone app use among US adults.
