Context
Users can access their vehicle's data only after connecting through Smartcar, a service that links the app to data from the car manufacturer.

Problem
Drop-off was high when users tried to add a car to the garage. They reached the paywall before understanding the app's core value and left without subscribing.
1. Adding a car before connecting to Smartcar
The goal was to lower the barrier to getting started by letting users add a car directly in the app before connecting through Smartcar.
Early tests showed that users did not always know where to start adding a car. I made the entry point more prominent, redesigned the home screen, and ultimately moved the first-car setup into onboarding.
2. Exploring demo vehicle data
I designed a demo mode for users who were not ready to add their own car but wanted to explore the vehicle data the app could provide.
3. Checking Smartcar compatibility
I integrated a compatibility check into the add-car flow so users would know earlier whether Smartcar supported their vehicle. After selecting a car, the flow branches into two paths.

Results
After launch, subscription conversion increased by 15%, and the number of cars added grew by 22%. We also reduced refunds and negative support requests.
