A. User Registration & Profile Setup

  1. Download & Install: Users download the app from the App Store or Google Play.
  2. Sign-Up: Users create an account using email, phone number, or social media login.
  3. Personalization: Some apps ask for shopping preferences to tailor deals (e.g., fashion, groceries, electronics).

B. Browsing & Searching for Coupons

  1. Categories & Filters: Users can browse deals by store, category (e.g., food, travel), or discount type (percentage off, BOGO).
  2. Search Functionality: Users can manually search for specific brands or products.
  3. Location-Based Offers: Some apps use GPS to show nearby in-store promotions.

C. Activating & Redeeming Coupons

    • Automatic Application: Some apps (like Honey) auto-apply the best coupon at checkout.
    • Copy-Paste Codes: Users manually enter promo codes at checkout.
    • Click-Through Links: Users click a deal, redirecting them to the retailer’s site with the discount pre-applied.
  2. In-Store Coupons

    • Barcode/QR Code: Users show a scannable coupon at checkout.
    • Loyalty Integration: Some apps sync with store loyalty programs for automatic discounts.

  3. Withdrawal Options: Users can redeem earnings via PayPal, gift cards, or bank transfers.
