Overview

A leading baseball training startup partnered with me to redesign its React Native iOS app — transforming a data-heavy tool into a clear, motivating, and athlete-centric experience. Over four weeks, I delivered a redesigned interface, design system, and developer-ready prototype that simplified motion tracking, performance insights, and training progress.

The Challenge

turning complex metrics into actionable training

Players and coaches struggled to navigate confusing flows and overly technical data. The onboarding lacked clarity, and visual inconsistency made it hard to connect performance results to real progress. The challenge was to create a visually polished, baseball-aware interface that guided users seamlessly through their training journey — from measuring motion to assessing metrics, training, and re-measuring improvement.

Solution

Designing an intuitive sports-specific journey

Through a focused UX review and rapid iteration in Figma, I streamlined the Measure → Assess → Train → Re-measure journey into a simple, motivating loop.

  • UX clarity: Redesigned navigation, simplified onboarding, and decluttered layouts.

  • Visual cohesion: Introduced a modular design system with baseball-inspired icons and iOS-native patterns.

  • Contextual feedback: Translated advanced metrics (like exit velocity and launch angle) into visual dashboards and color-coded insights for instant understanding.

Outcome

A redefined digital training companion

The redesigned app delivers an experience that’s clear, fast, and built for athletes. With intuitive flows, modern visuals, and accessible metrics, players can now see their progress in real time — and developers have the tools to bring it to life efficiently.

“The new design feels built by baseball people — everything just makes sense now.”

Impact & Next Steps

The redesign set a new visual and usability standard for the client’s platform, enabling smoother onboarding and faster iteration. Future work includes real-time coaching feedback, expanded web dashboards, and integration of AI-based performance insights — bringing the same simplicity to more players and coaches worldwide.
