Backgound
Zepp’s existing workout history was organized in a linear timeline format—displaying sessions chronologically without offering broader temporal context. While functional for reviewing individual workouts, the system lacked flexibility for planning ahead or identifying trends across time. As Zepp continued expanding its training ecosystem and AI capabilities, the existing structure limited the product’s ability to support more strategic, data-informed athletic progression.
Core Features
01
Calendar-Based Training System
User Pain Point
Workout history lived in a linear timeline that lacked context. Users couldn’t easily see distribution across time or switch between daily, weekly, and monthly perspectives.
Our Solution
Redesigned workout history into a dynamic calendar system with seamless daily, weekly, and monthly views. This structure provides temporal clarity at multiple scales—allowing users to zoom in on a single session or step back to understand overall training patterns.
02
Add & Edit Workout Plans
User Pain Point
Workout entry was restricted and inflexible, limiting user autonomy in planning and adjusting their training schedule.
Our Solution
Enabled flexible workout planning from multiple sources—including custom entries, Zepp Coach AI, training library presets, and third-party platforms. Users can further schedule or edit workouts as needed.
03
Week-In-Review Workout Summary
User Pain Point
Users struggled to connect planned workouts with completed sessions and lacked a clear weekly overview of performance.
Our Solution
Introduced a system that displays planned vs. completed workouts across each day and time slot. High-level stats are surfaced at a glance, with tap-to-drill functionality for deeper workout data — making weekly progress easy to assess.
04
Weekly/Monthly Performance Summaries
User Pain Point
Although workout data was available, users lacked cumulative insights and meaningful comparisons across weeks or months to understand progress.
Our Solution
Designed scalable performance summaries that function across both weekly and monthly views. Users can:
View cumulative performance up to a selected date
Compare day-to-day or week-to-week trends
Evaluate month-over-month progress
05
Bonus Features
AI Pick
A smart highlight stat that surfaces the most meaningful performance insight for the selected week or month.
Customizable Summary Metrics
Choose which workout metrics appear front and center—tailoring performance summaries to individual training priorities.
Workout Type Filter
Filter the calendar by workout type to compare cumulative performance across specific training categories.

Design Process
Prioritizing Features and Structuring Product Logic Through UI
Working from an existing PRD and tight launch timeline, I translated high-level feature requirements into cohesive, interactive prototype screens. By clarifying UX logic and mapping product intent directly into UI behavior, I ensured that planning, tracking, and performance insights could coexist within a unified calendar system.
Expanding the Design System for a Flagship Feature
Because the calendar system introduced new interaction patterns and summary logic, it required components that did not yet exist in Zepp’s design library. I refined new UI elements to ensure the feature felt like an evolution of the product rather than a visual departure.
Reflection
01
Introduce milestone-based planning beyond workouts
Allow users to add custom milestone events—such as races or personal commitments—to anchor their training schedule around meaningful goals.
02
Expand comparison beyond fixed parallel time ranges
Enable more flexible, user-defined comparison points (e.g., custom range A vs. range B) to support personalized performance evaluation.
03
Standardize temporal framing across all workout templates
Extend scheduling logic to third-party and preset workout templates, ensuring consistent time allocation and seamless calendar integration across the ecosystem.
04
Enable drag-and-drop schedule adjustments
Allow users to move planned workouts directly within the calendar interface, reducing friction compared to manual edit flows.
