Gentari is an electric vehicle mobility app designed to simplify EV charging, scooter reservations, route planning, and sustainability engagement. The platform combines practical charging infrastructure with interactive features that encourage eco-friendly behaviors. My role was to lead the full product design, optimizing both the user experience and retention loops to drive recurring usage and build user loyalty.
Role:
Lead Designer
Industry:
EV Infrastructure, Mobility Tech
Duration:
8 Weeks
Challenges
Complex user journeys for EV drivers who need multi-step planning across route, charging, and availability
Limited early user motivation to engage with non-essential features beyond basic charging
Lack of ongoing engagement mechanisms to bring users back after their first charging experience
My Approach
Simplified the EV charging journey by integrating route planning, live station availability, and real-time pricing into one unified search flow
Designed an intuitive scooter reservation feature that allowed fast nearby discovery with live location-based selection and dynamic ETA calculation
Introduced energy usage tracking with data visualization to build user awareness and strengthen value perception after initial use
Integrated the Handprint sustainability initiative where users can plant trees based on charging usage, building emotional reward loops and deeper retention
Developed a friendly in-app AI chatbot that supports trip planning, answers charging questions, and reinforces green impact in a conversational way
Results
Improved first-time user flow completion, reducing friction from search to charge initiation
Increased repeat engagement through tree-planting gamification and personalized energy tracking
Strengthened brand loyalty by positioning sustainability not just as infrastructure but as a personal contribution metric
Created multiple re-engagement hooks across route planning, energy savings, and environmental rewards
Conclusion
Gentari was a true growth experience in combining mobility, sustainability, and behavioral design. Every feature was designed to make green mobility feel actionable, rewarding, and habit-forming. This project sharpened my ability to design for long-term retention by building emotional reward systems tied directly to product usage.
