As the first commercially available smartphone app for EDs, Recovery Record (RR) has established wide reach and user acceptability. The app provides users with meal and ED symptom self-monitoring and coping skill strategies in an evidence-based CBT format. Preliminary pilot data suggest that for a proportion of RR users, using RR is associated with clinically significant symptom reduction. However, a limitation of the current app is that it is a "one-size-fits-all" product that does not account for the heterogeneity of ED symptoms. Genetic, personality and neurocognitive data support distinct clusters of ED presentations that also differ according to response to treatment, course and outcome. Pilot data confirm that clinical response to RR is not homogenous across groups and that extent of cognitive distortions is the most potent factor to predict outcome. There is considerable opportunity to increase RR's effectiveness across a range of ED symptoms and behaviors by creating adaptive and tailored content focused on remediation of cognitive distortions.
