PROBLEM STATEMENT

Users in the mental health space often lack personalized, data-driven tools that help them consistently track progress and improve emotional well-being.

While users initially found the science behind Matter intriguing, our research revealed a key insight: scientific credibility alone wasn’t enough. The real challenge lay in translating these insights into daily habits that users would stick with.

This realization shaped our approach during the beta testing phase, where two primary challenges emerged:

  1. Low Onboarding Conversion: Users did not upload their first memory during onboarding due to unclear value propositions.

  2. Inconsistent Engagement: Although users appreciated the science, they lacked the motivation for continued use.

RESEARCH GOALS

RESEARCH GOALS

With the target persona defined and the public beta underway, our next step was to uncover why users weren’t engaging as expected. Our research aimed to bridge the gap between user curiosity about the science and the formation of daily mental health habits.

The research was driven by four primary goals:

  1. Identify the Root Causes of Low Onboarding Conversion

    • Determine why users were dropping off early, particularly during the first memory upload, and how to improve initial engagement.

  2. Understand User Motivations and Barriers

    • Explore what drives sustained engagement and habit formation in a mental health context, focusing on how users integrate the app into their daily routines.

  3. Iteratively Refine Core Features

    • Ensure that updates and new features align with user needs, increasing the likelihood of long-term usage and habit formation.

  4. Continuously Gather and Apply User Feedback

    • Maintain a robust feedback loop through in-app feedback, interviews, and usability testing to inform rapid iterations and address pain points promptly.

These goals informed a structured, multi-phase research plan designed to uncover actionable insights, validate hypotheses, and refine Matter into a habit-forming mental health tool.

KEY FINDINGS & IMPACT

Persona Evolution: A Key Insight

Through the research process, our understanding of the target persona evolved significantly. While the initial persona reflected users interested in neuroscience-backed mental health approaches and digital well-being tools, research revealed:

  • Less Exploratory, More Goal-Oriented: Users had less of an exploratory approach to neuroscience for well-being. Instead, they sought goal-tracking methodologies (e.g., daily ring features) that fostered regular habit-building.

  • Importance of Habit Formation: This shift was crucial because consistent daily engagement is essential for meaningful mental health outcomes. Users wanted tangible daily progress indicators, emphasizing structured engagement over exploratory learning.

This key insight directly influenced the prioritization of habit-forming features such as the Ring Goal, ensuring the app fostered regular usage patterns essential for improving mental health.

Key Differences from Initial Persona:

  1. Shifted from exploration-focused to achievement-focused

  2. Prioritizes habit formation over scientific understanding

CONTEXT

The Matter app was built on a simple yet powerful idea validated by our clinical trials: reflecting on positive memories can rewire the brain for happiness. Grounded in neuroscience, Matter aimed to help users strengthen neural pathways linked to joy and emotional resilience.

But the challenge was clear—turning science into a daily habit requires more than good intentions; it demands clear daily motivations and personalized guidance.

I joined the company as it was kicking off its public beta, leading UX research efforts that shaped the product’s evolution by uncovering key engagement barriers and informing critical product decisions.

Core Concept & Science

Before launching the public beta, we introduced users to the neuroscience-driven foundation of Matter. Our goal was to build trust by clearly showing how reflecting on positive memories could rewire the brain for happiness and emotional resilience.

The concept centered on three key pillars:

  • Reflecting on Positive Moments: Strengthens neural pathways associated with happiness.

  • Science-Based Credibility: Neuroscience-backed insights build user trust.

  • Trackable Progress: The Matter Score provides a tangible way to monitor emotional well-being.

These frameworks, including MRI-based emotion mapping, neurotransmitter tracking, and personalized memory uploads, set user expectations before beta testing—expectations that would later inform our research approach.
