“Personalized Daily Deals & 1-Tap Store Activations”

The Friction / User Pain Point

Users were overwhelmed by generic banners, cluttered category carousels, and couldn't immediately tell how much real cashback each store offered.

UX Improvement Implemented

Redesigned the entire hierarchy with high-contrast cashback pills (e.g. 'Up to 12% Real Cash'), quick flash-deal countdown timers, and sticky top-store quick filters (Flipkart, Myntra, Ajio).

Measurable Outcome & Impact

+38% click-through rate from the home feed and 45% faster store discovery for new users.

Key Technical & UI Highlights:

  • Dynamic flash sale countdown tickers
  • One-tap store activation deep links
  • Verified deal tags with live percentage badge
  • Personalized store recommendation rail
