The Problem

Vitreus needed a mobile app serving two very different user mental models: crypto wallet users (send/receive tokens) and vNode operators (manage IoT hardware). These are fundamentally different audiences with different needs in a single app.

The Process

Original design was immersive-a video game HUD with dynamic visual feedback correlated to VNRG mechanics, a quickswap button to 'play' with energy conversion, customizable UI elements. Budget constraints simplified the vision. Dev team proposed two separate apps; I kept it unified as designed, adding complexity but delivering a cohesive experience.

The Outcome

Shipped to iOS and Android. 1 major + 10+ minor updates post-launch. Successfully serves both wallet users and node operators. The plug-and-play vNode flow required extensive remote troubleshooting with the dev team.

Design Decisions

Decision Why Engineering Tradeoff
Unified app vs. two apps Reduces maintenance burden, shared auth More complex state management
Tab-based navigation Clear mental model separation Requires conditional rendering
Offline-first for vNode status Users in areas with poor connectivity Local caching complexity

STAR Summary

SituationVitreus needed a mobile app for two very different user types: crypto wallet users (send/receive tokens) and vNode operators (manage IoT hardware). Different mental models, different tasks, different technical sophistication-in a single app.
TaskAs Product Owner, deliver a unified mobile experience. Dev team proposed two separate apps; I needed to justify and execute a single-app strategy that served both personas without confusion.
ActionDesigned tab-based architecture separating wallet and node functions while sharing auth and common infrastructure. Built offline-first patterns for field operators with poor connectivity. Ran weekly design reviews with engineering; caught critical state management issues early. Coordinated extensive remote troubleshooting for plug-and-play vNode flow.
ResultShipped to iOS and Android. 1 major + 10+ minor updates since launch. Successfully serves both user types. Unified approach reduced maintenance burden and accelerated feature development through shared components.

Worth it. Conditional rendering based on user type needed careful architecture, but maintenance savings justified upfront complexity.
