Context
Users had a 30% error rate dismissing alarms, timers, and reminders, often unintentionally postponing them, and struggled with syncing recurring features across devices.The goal was to refine Alexa’s time management system for better accuracy, control, and ease of use.

"Alexa, check my Fire TV reminders"
Visibility & management across devices
Enabled seamless recurring time management across Alexa devices, allowing users to set, modify, and cancel time features effortlessly on Fire TV, Echo Show, and Alexa Mobile.

Aligned with domain teams to scale the experience across devices, modalities, and interaction paradigms, ensuring seamless interaction via voice, touch, and remote control.
