That page also will tell users how many apps they have on each device, as well as which percent are free and which are paid, as well as the total current monetary value of the paid apps.
Which gets to the other tool that will make the Google Play experience more rewarding for users: Google Opinion Rewards.
About 90% of downloaded mobile apps are free, and that percentage is expected to rise -- apparently, people rarely are willing to spend even half the amount they'd spend on a Starbucks run for an app that might pay for itself in two days.
I'm no different. Four of the 82 apps on my Nexus 7 tablet are paid apps, while only one of 110 on my HTC One cost me money (total: $17.15).
Part of this is digital economy conditioning -- we've all become accustomed to free -- and part of it is that people are hesitant to spend money on something if they're not sure they're going to use or even keep it. There are a lot of crappy applications out there.
But if you download Google Opinion Rewards, you have an opportunity to build up credits to use in Google Play merely by participating in brief surveys. You get credit for $1 for each survey. Google spaces them out to about once a week, but over time users will be able to download some of the paid apps they've been coveting without spending money.
