Phase 3

Dark Mode Enhancement

To align with the mission of Fin's parent company, AAA, the app sought to promote safe driving for Fins Car Wash customers. Implementing a dark mode was crucial as bright screens could distract drivers at night and impede their ability to readjust to low-light surroundings.

Phase 3


  • Encouraged safe driving by introducing a dark mode feature

  • Defined a new color palette and updated the design system

Phase 4

License Plate Recognition Technology Integration

Fins implemented new license-plate reading capabilities at car wash locations to track loyalty purchases and wash club member activity. This technology also empowered kiosks to display personalized menu options based on users' loyalty, AAA, or wash club status.
