PilaBit is designed to make Pilates a lasting part of daily life. Many people struggle to stay consistent with existing apps, which often lack personalized plans, habit-tracking, and motivation features—making it difficult to stay engaged.

PilaBit solves this problem by combining personalized workout plans, progress tracking, and an AI Coach that adapts workouts in real-time. With a built-in community and goal-oriented challenges, PilaBit makes Pilates more engaging and easier to maintain long-term.

'Make Pilates Your Habit'—More than just an app, PilaBit is a companion for consistency and a healthier lifestyle.

The Problems

Pilates enthusiasts struggle with consistency and motivation

Even though Pilates apps are growing, keeping users engaged is still a big challenge. By talking to users and analyzing other apps, I found three main issues:

'Lack of Personalization'

'Inconsistent Engagement'

Without tracking or feedback, users struggle to see progress, leading to low motivation.

'Limited Connection'

Lack of community features make workouts feel isolating, unlike in-person classes.

The Goal

PilaBit customizes workouts that adjust as users progress while fostering a supportive community. By combining motivation with simple, easy-to-follow routines, it keeps users engaged and helps them stay consistent with their Pilates goals.

Reflection

What I Learned from This Project

This project taught me the importance of personalization and AI in fitness apps. Users want tools that adapt to their goals, not just generic programs. I learned how to turn user feedback into real solutions and saw that good design is more than looks—it's about usability and impact.

I also realized how small design choices can make a big difference in user experience. Refining the goal-setting process, improving progress tracking, and integrating social motivation features all plated a role in marking the app more engaging and intuitive.

If I Had More Time, What Would I Improve?

If I had more time, I'd explore ways to integrate adaptive recovery. Most fitness apps focus on activity, but recovery is just as important. A feature that suggests light mobility exercises or guided stretching based on user activity could add more value.

Instead of just telling users to rest, the app would suggest light recovery sessions like gentle stretching and breathwork. If a user has been doing intense workouts, their plan would adjust automatically, providing low-impact routines to keep them engaged while recovering.
