Objective: Narrative objectives1 - To examine whether the Watch Me app, a smartphone application implementing parent-training techniques, produces a greater short-term reduction in young children's screen time than an active comparison condition (psychoeducation plus a diary-only version of the app).

Intervention: Interventions/Control_1 - Watch Me group. Participants used the Watch Me smartphone app, which implements evidence-based parent-training techniques (e.g., narration with praise), for 7 days. Parents performed and recorded daily narration with praise toward their child and logged the child's daily screen time. Human support was limited to initial onboarding; no ongoing coaching and no push notifications were provided. Interventions/Control_2 - Active comparison group. Participants received psychoeducation and used a diary-only version of the app for 7 days.
