Project Overview
A mobile app was created to help football fans and athletes improve their penalty kicks using AI and computer vision. The app measures ball speed, spin, and trajectory using only a smartphone camera and lets users compete with others worldwide.
Problem & Goals
The original version of the app had serious technical debt, making it unscalable, difficult to maintain, and not suitable for presentation to investors. The goal was to:
Redesign the UI for better clarity and usability
Rebuild the app to match investor expectations and ensure global scalability
Enable real-time video analysis using only a smartphone camera
Support a seamless experience for both casual users and professional athletes
Process & Solution
Researched user needs and identified gaps in the previous version
Mapped key flows for recording, competition, and feedback
Developed a bold, sporty visual style and consistent design system
Designed an interface for video capture, scoring, and AI feedback
Delivered interactive prototypes to validate core user journeys
Outcomes & Metrics
Live in the App Store with stable performance and strong usability
Used by 50,000+ players at the Norway Cup
Adopted in daily training by both amateur and pro players
Users praised its simplicity and motivating competitive features
Next Steps
After launching the redesigned MVP, the next steps involved tracking key engagement metrics such as session frequency, feature usage, and competition participation. The team planned to run usability testing with both amateur and professional players, gather qualitative feedback on video analysis features, and analyze drop-offs in recording and scoring flows. Insights from real-world usage would guide the next iteration focused on refining AI feedback, expanding training modes, and optimizing the app for consistent, long-term engagement.
