Two design recommendations (digital nudges) for decreasing user churn in mobile apps are presented. We examine commitment and personalization nudges, both of which are linked to the extant literature, in the context of a randomized online experiment with 150 participants. Our experimental study reveals that commitment and personalization cues distinctly affect consumers' intention to use a mobile app. Moreover, our study demonstrates that personalization amplifies the effect of commitment cues on users' intention to use a mobile app.
