AI-Powered Assistant for 1ForFit Apps

The Challenge

At 1ForFit, a company dedicated to building digital health and wellness solutions, we aimed to enhance user engagement by integrating an AI-powered personal assistant chat into our mobile app. The goal was to provide users with seamless, expert-backed advice on nutrition, fitness, psychology, and dieting - all within an intuitive chat experience that felt as natural as talking to a real expert.

The challenge was twofold:

- Creating an authentic, human-like chat experience that made users feel they were speaking to real professionals.
- Determining the best interaction model to balance AI-driven guidance with user flexibility, ensuring an engaging and valuable experience.

The Solution

We crafted a user-friendly chat experience inspired by familiar messaging platforms, ensuring a smooth and intuitive interaction. The chat feature was strategically placed in the app’s top navigation bar, allowing users to effortlessly start a conversation with their preferred AI expert at the tap of an icon.

Three Chat Interaction Models

We tested three different approaches:

1. Predefined Questions & Answers. Quiz-Style has already known behavior in the onboarding process among our users.

• Users were guided through structured questions with multiple-choice responses.
  
• Ensured clear, accurate, and easily digestible expert advice.
  
• Best suited for users who preferred quick, structured guidance.

2. Open-Ended Chat

• Users could ask any question, receiving responses in a free-flowing conversation.
  
• Created a highly personalized experience but posed risks of AI misinterpretation.
  

3. Hybrid Approach (Predefined + Open-Ended Chat)

• Combined structured prompts with free-text input options.
• Allowed for both guided learning and flexible exploration of expert advice.
  
• Balanced usability and personalization, addressing limitations of the other two models.
  

Our iterative approach, backed by A/B testing and data-driven insights, revealed that the hybrid model delivered the best results.

Key outcomes included:

- 30% increase in user engagement within the first three months.
- Higher retention rates, as users found value in tailored, interactive advice.
- Improved conversion rates, as personalized advice encouraged users to explore premium app features.
