Project Background

Our team of two UX designers partnered with Trime, a fitness tracking app that helps users stay consistent with their workouts. Over four weeks, we worked in two main phases, user research and prototyping.

Trime came to us with a goal:

Improve user retention by making fitness tracking more engaging and actionable.

The Challenge

Like many fitness apps, Trime struggled with long-term user engagement. Key issues included:

  • A cluttered onboarding process that overwhelmed new users
  • Disorganized navigation, making it hard to track progress
  • Booking training sessions was confusing

We believed that to attract a broader audience, the app needed to feel less competitive and intense—and instead become more playful, human, and understanding.

The Process

User Research

We conducted interviews with both current and potential users of Trime to understand their pain points, goals, and habits. From the insights gathered, we:

  • Created four detailed user personas
  • Simplified the information architecture
  • Mapped out new user flows
  • Built empathy maps and other key research artifacts

After presenting our findings to Trime, we got the green light to move into prototyping.

Prototyping and Solutions

1. A Playful, More Human Onboarding

We redesigned the onboarding to feel more like a conversation and less like a form. Users set up their profile in a way that also helps match them with the right personal trainer, turning onboarding into something helpful, not just necessary.

2. Shifting the Focus: Book a Session First

Booking a session is one of the app's most essential features but it was buried. We redesigned the interface to prioritize training times and easy booking, right at the top of the home screen.

3. Your Personal Checklist

Users told us they sometimes opened the app and weren't sure what to do next. Our solution, a personalized checklist that gives users a sense of progress, even on days they don't have a session scheduled.

4. A More Human Rating System

The old rating system felt cold and impersonal. We replaced it with one that encourages thoughtful feedback, making the post session experience more human and less like a transaction.

Outcome and Impact

While we didn't have time to track quantitative metrics, user testing and qualitative feedback showed meaningful improvements:

  • ✅ Onboarding felt more supportive and approachable
  • ✅ Navigation was cleaner and more intuitive
  • ✅ Users felt more motivated to stay consistent

If we had continued with the project, our next steps would include A/B testing onboarding flows and measuring retention and session booking rates.
