Motion-First UX Conversion for the World’s Smartest Fitness Studio
Extend cutting-edge in-studio experience to mobile while driving feature adoption and retention
About Our Client
Lumin Fitness is a tech driven boutique brand known as “the world’s smartest fitness studio.” It offers AI coaching and motion tracking for personalized group workouts, blending personal training with group energy. Lumin aims to bring this innovative experience to its mobile app.
Lumin Fitness Studio, Texas
Problem
Despite Lumin’s innovative in-studio tech, the mobile app was lagging behind. The app’s UI had become outdated and key user flows were buried deep in the information architecture. Lumin needed a redesign to surface critical features upfront, modernize the look and feel, and integrate AI guidance more clearly into the user experience.
Static, outdated UI: No visual feedback for user actions, creating uncertainty around input registration
Poor task efficiency: Core workflows required 5+ taps and 25+ seconds
Hidden features: Key personalization features and workout recommendations are buried in navigation
Precious Approach
Precious Studio partnered with Lumin through our subscription model to tackle these issues. We adopted a sprint-based approach, working closely with Lumin’s product and engineering teams via Slack messages and huddles for rapid feedback loops.
Solution: Motion as a Conversion Tool
AI Guidance Layer
Introduced contextual micro animations to highlight AI assistance without disrupting flow. Visual cues distinguish AI actions from user actions.
Purposeful Motion Design
Every animation serves a function. confirming actions, signaling state changes, directing attention.
Celebrated Micro Interactions
Designed dopamine-triggering animations at key success moments. Motion design amplifies positive reinforcement, creating habit-forming feedback loops that drive retention.
Responsive Rive Animations, Blender 3D Motion, and Lottie Integrations
Technical Execution & Pipeline
We implemented a hybrid animation strategy optimized for performance and flexibility. Interactive, state-driven animations used Rive's state machine architecture allowing designers to embed interaction logic directly into animation files. This eliminated developer guesswork and ensured pixel-perfect implementation of complex behaviors like animation states, loading sequences, and AI activation triggers.
Simpler, looping animations deployed via lightweight Lottie files. Our Designers delivered implementation ready Rive files with pre built state machines, reducing developer cognitive load and enabling same day bug fixes and reviews through Slack + Rive collaboration.
Final Lumin App Implementations
Impact: How We Accelerated Lumin's Team
Same-Day Issue Resolution
Developers reported animation inconsistencies or design token adjustments via Slack; Precious delivered fixes within hours. Quick turnaround eliminated development bottlenecks and kept sprints on schedule.
Zero Animation Logic for Developers
Precious built all Rive state machines inside animation files. Developers simply triggered states via API calls no custom animation code required. Reduced cognitive load and ensured pixel-perfect implementation.
10x Smaller Asset Sizes
Converted 60KB Lottie animations bundle to a single 5KB Rive files. Smaller bundles meant faster load times and minimal memory impact, allowing richer motion without performance tradeoffs.
Implementation Ready Deliverables
Figma tokenized design system, Rive .riv files, Lottie JSONs, and motion guidelines delivered sprint aligned. Developers received exact specs with usage notes no subjective interpretation needed.
Responsive Animations Out-of-the-Box
Rive's built-in layout features made animations automatically adapt to different screen sizes. Single animation file worked across mobile, tablet, desktop without developer adjustments or multiple versions.
Proactive UX Improvements
Precious identified and redesigned suboptimal user flows from original specs, simplifying navigation sequences with animated transitions. Changes communicated with clear rationale, final product exceeded initial requirements without scope creep.
Key Takeaways for Product Leaders
How motion design accelerates growth velocity while creating engagement-driving user experiences.
Motion drives measurable outcomes: When animation serves a purpose, it improves conversion and retention – not just aesthetics. Every motion element should map to a user goal.
Make AI interactions visible: If your product has AI features, give them clear visual presence with motion feedback. Users adopt what they can see and understand. Hidden intelligence is wasted technical investment.
Performance is non-negotiable: Set explicit performance baselines and asset size budgets upfront. Tools like Rive enable rich interactions at minimal cost. Discipline around constraints yields interfaces that feel as edgy as they look. Nobody likes lags.
