As the sole freelance designer for Rutin, I collaborated directly with the app owner to transform an early-stage concept into a clear, functional MVP for health coaching and habit tracking. By mapping the information architecture early on, I established a focused scope that streamlined the core user flows and prevented feature bloat. My primary objective was to deliver a complete design foundation, including a comprehensive design system, component library, and high-fidelity screens ready for handoff, ensuring the final product was lightweight, approachable, and easy to navigate for everyday users. Visually, I crafted a calm and supportive atmosphere using a palette of soft purples and warm neutrals, reinforced by rounded shapes and subtle motion to make daily habit-building feel less overwhelming. I designed a cohesive set of components, from stable navigation bars to digestible task cards and custom iconography, maintaining a gentle tone throughout the Home, Journal, Habits, and Community screens. To keep the MVP efficient for development, I made deliberate design tradeoffs, such as limiting deep customization and complex filters, prioritizing clarity and ease of entry to foster consistent, long-term user engagement.

The Problem

Most health apps overwhelm people with data and dashboards, which makes building simple daily habits feel like work rather than support.

Approach

Information Architecture

I mapped the information architecture early to establish a focused scope — streamlining the core user flows and preventing feature bloat.

Design System & Components

I built a comprehensive design system and component library — stable navigation bars, digestible task cards, and custom iconography — kept consistent across the Home, Journal, Habits, and Community screens.

A Calm, Motivating Atmosphere

I crafted a calm, supportive feel with soft purples and warm neutrals, rounded shapes, and subtle motion, so daily habit-building feels less overwhelming.

Solution

Delivered a complete MVP design foundation — design system, component library, and high-fidelity screens — that lifted average user retention from 28 to 40 days.
