Bridging Mobile & Desktop: Redesigning Whistle’s Selling Experience for Increased Conversions

Whistle, a leading resale platform for electronics, relied heavily on its mobile app. However, during COVID-19, desktop usage surged as users preferred larger screens for product listings and transactions.

The Challenge

• ❌ The desktop experience lacked a direct selling flow, forcing users to download the mobile app.
• ❌ Lost conversions as users abandoned the process when redirected to a mobile device.
• ❌ No optimised checkout flow due to the lack of a dedicated desktop checkout led to low completion rates.

As the main product designer, I adapted Whistle’s mobile-first experience into a seamless desktop selling flow, ensuring feature parity and frictionless user engagement

My Solution

• ✅ Adapt the mobile flow for desktop to provide a fluid experience.
• ✅ Enable users to sell their old device on desktop.
• ✅ Convert otherwise lost desktop traffic to convert into registered users.

Learnings & Next Steps

• Users expect seamless multi-device experiences
• Pricing transparency improves conversions
• Progressive disclosure minimises errors
