From the nested quote that the forum software left out: 25% of users install an app and only use it once. I wonder, what percentage of those users are doing so not because they don't like the app, but because another app gave them incentive to try it? I personally use very few apps on my phone, but one of them has microtransactions. The in-game currency is coins. You can get these coins by signing in every day, winning contests, buying them, watching ads or trying some other app. I doubt that this is uncommon. So I wonder how many people are just doing the bare minimum required (it varies) in order to get the coins or whatever they need for the game they are playing.
