This Forrester Research, Inc. report focuses on mobile tactics and technologies marketers can use to transform the customer experience.

User acquisition costs are at an all-time high (~$3 a pop according to Fiksu), so attaining and retaining app users is key. But for brands like Zillow and eHarmony, succeeding at doing so comes at a cost — an always vanishing customer base. In the fourth Mobile Saturday panel, “When Success Means an Always Vanishing Customer,” panelists discussed effective acquisition strategies for their brands and techniques to cater to different customer groups for an improved experience.

“User utility is everything.” That, in a nutshell, was the key takeaway from Urban Airship’s fourth Mobile Saturday event at SXSW 2016, an annual gathering of industry thought leaders focused on what’s next in mobile. And that should come as no shock — or should it?

Following are some of the top observations and trends to help guide your path forward in the months to come.
