How I Enhanced Engagement for a Gamified Mental Health App

🧩 Context

LePal.ai is a gamified, AI-driven mental health app for Gen Z. Users can use 8 core features including logging their moods, writing journal entries, and interacting with AI-based 'spirit pets' that offer support and insight.

📝 I was tasked with:
  • Understanding the user base and barriers to and motivation for engagement
  • Enhancing the mood tracking feature
  • Increasing user retention and optimizing monetization

🗓️ Duration

2 Months
(split into 2 phases — research & design)

The Challenge

Despite LePal’s unique gamification elements, retention dropped sharply after onboarding.

User behavior showed:

📉

  • High bounce rates after first few sessions

📓

  • Limited engagement with key features like the mood tracker and journaling

🫤  

  • Lack of motivation to return daily or upgrade to premium

Key Business Goals:

📈

  • Boost retention & daily active usage

💰

  • Improve the perceived value of the app (freemium to premium conversion)

  • Create a clear sense of progress and value from the start

My Process

🔍 User Research

To improve engagement and design monetization strategies, I recruited users to use the app for 7-10 days and provide feedback on their overall experience, the usability of specific features, their willingness to pay, the ideal customer profile, and any changes they would make.

To do this, I used these methods:
🔑  Incentivized Users

           Offered a  free 3-month premium subscription and access to exclusive            Discord community upon successful completion of study

🫱🏽‍🫲🏼 Recruited Users

           Via LinkedIn, Instagram, Tik Tok, and professional community outreach           

❓ Screened Participants

      Via 18 screener surveys to determine participant eligibility                           

🗣️  Interviewed Users

      6 initially, 2 heavy users re-interviewed                                                 

Using the above methods, I uncovered these key insights:
🧠 Users were engaged by:
  • Spirit pet interactions and quests
  • Points, rewards, and visual progress
  • Daily checklists (quests)which reinforced habit loops
😵 Users dropped off due to:
  • Technical bugs, slow load times, and confusing navigation
  • Journaling and mood tracking felt repetitive or lacked personalization
  • AI-driven spirit pet sometimes gave surface-level or insensitive feedback
"It (spirit pet) told me to 'just chill out'... that wasn't helpful."
💸 Users hesitated to convert to a paid subscription because:
  • Free features felt too limited, but users didn't see enough value in upgrading
  • Users wanted tangible benefits (e.g., therapist chat, deeper insights)
  • Most weren't willing to pay without seeing emotional or functional payoff
"I'd rather spend $4 toward a real therapist."

I flagged my PM about the technical bugs and slow loading times, which was an issue for the developer team. I also notified my PM that the LLM for the AI-driven spirit animal needed to be trained further to give more in-depth and sensitive feedback. The remaining insights on user drop-off and monetization barriers were more design-related issues. In response to those, here are 2 solutions I proposed:

1. 🔥 Competitive Social Streaks

A gamified leaderboard to motivate daily engagement with XP, badges, and tiered streaks

  • Weekly XP competitions to unlock 'spirit pet' accessories
  • Optional buddy streak for lightweight social accountability

Why this would work:

"I wouldn't want to break a streak with a friend. That would keep me coming back."
2. 🌱  Personal Growth Tracker

A goal-oriented journey map to journaling and mood tracking.

  • Weekly summaries with mood trend visualizations
  • Custom avatars + 'spirit pet' evolution based on consistency
  • "LePal Reflections" — AI-generated feedback after journal entries
"This (personality insights) feel's more personal. I like it—it gives me feedback and shows what to focus on."

🧪 Usability Testing

Ultimately, I was tasked with redesigning LePal’s mood tracker to prioritize simplicity and emotional clarity. The updated screen allows users to:

I tested the prototype with 15 naïve users unfamiliar with LePal. Here is what I found:
