Over 90% of smartphone owners use apps, and 72% of app users churn within the first three months of installing a new app. As marketers reevaluate acquisition programs, shifting payment down the funnel from installs to engagement, the approach should be centered around the consumer experience.
Focusing on minute optimizations of marketing and UX alone largely neglects users and user experience, from high-level acquisition through down-funnel engagement in-app. Marketers and developers alike have forgotten that a smartphone is likely treated as more of an appendage than an accessory. Phones are highly personal devices, filled with carefully organized and curated applications intended to make life easier (e.g. maps, banking, email) or fun (e.g. games, social media, shopping).
