Overview
Posture Perfect is an AR-powered fitness application designed for at-home workouts. The product addresses a real gap in the market: guided workout apps exist everywhere, but none offer real-time posture correction feedback — the feature that reduces injury risk and keeps users engaged long-term.
The Problem
Post-pandemic, home fitness shifted from necessity to lifestyle. Yet the apps serving this audience were built around video libraries and static images — with zero feedback on whether users were actually doing movements correctly. The result: users either got injured, felt unmotivated, or both.
"Online workout videos are not tailored as per my needs and goals."

Research
We conducted in-depth user interviews and surveys targeting both regular fitness enthusiasts and people trying to build a home workout habit. Three dominant themes emerged:
Flexibility
Users wanted to work out on their own schedule without gym dependency.
Social Anxiety
Many avoided gyms due to self-consciousness — home felt safer.
Pricing
Gym memberships and personal trainer costs were prohibitive barriers.
No Real-time Feedback
The absence of posture correction was the single biggest gap in existing solutions.
User Persona
From our research we developed "Mom Madeline" — a working parent who wants the efficiency of home workouts without sacrificing safety or motivation. Her needs anchored every design decision: convenience, real-time guidance, and gamification elements that kept her coming back.
Design Process
We moved from context scenarios through sketching, wire blocks, and low-to-mid fidelity wireframes — each iteration grounded in Madeline's documented scenarios. The sketching phase focused on four core flows: choosing workouts, performing movements with AR feedback, tracking progress, and motivational elements.

Usability Testing & Issue Resolution
We ran structured usability testing with 8 participants across three issue matrix cycles. Each cycle identified problems, rated them by impact and frequency, and drove specific design changes:
Issue Matrix 1
Play/heart icon confusion, missing workout filters, readability problems on-screen during exercise.
Issue Matrix 2
Two simultaneous timers confused users; no body scan indication; continued readability issues.
Issue Matrix 3
Live feedback popups were distracting; silhouette should always show correct posture; no completed exercise indicator.
Platform Pivot
Critical feedback led to the most significant decision: switching from mobile to TV app. A bold call — and the right one.
Final Designs
The final product delivers a TV-optimized AR fitness experience with a live instruction screen, real-time posture correction overlays, and a wind-down session post-workout. The design system ensures visual consistency across the experience.

Challenges & Learnings
The most significant challenge — and the most valuable learning — was executing a full platform pivot mid-project. Switching from mobile to TV app based on user feedback required rebuilding interaction patterns from scratch. It was uncomfortable. It was also exactly what user-centered design demands: following the evidence, not the original plan.
Coordinating across time zones within the team strengthened our async collaboration habits — a skill that translates directly into distributed product team environments.
