Executive Summary
A growing fashion retailer with 200+ stores and $50M in annual revenue wanted to expand their digital presence with a mobile app that could compete with major e-commerce platforms. They were losing market share to online competitors and needed a differentiated mobile shopping experience that could drive both online and in-store sales.
Codynex delivered an AI-powered mobile shopping app that revolutionized their digital strategy. Within 6 months of launch, the app drove 180% increase in online sales, 45% growth in average order value, and brought 30% of app users back to physical stores—creating a true omnichannel experience.
The Challenge
The client faced intense competition in the digital retail space and struggled with several critical challenges:
Key Pain Points
- Generic Shopping Experience: Their existing website offered the same experience to all users, failing to engage customers personally
- Low Conversion Rate: Only 1.2% of website visitors completed a purchase—well below industry average
- Cart Abandonment: 78% cart abandonment rate due to complicated checkout and lack of personalization
- Disconnected Channels: Online and in-store experiences were completely separate—customers couldn't seamlessly move between channels
- Limited Mobile Experience: Mobile-responsive website wasn't enough—customers expected native app functionality
- Inventory Challenges: No real-time inventory visibility across stores, leading to disappointing out-of-stock experiences
Business Goals
The client set ambitious targets for the mobile app:
- Increase online sales by 100% within 6 months
- Achieve 200,000 app downloads in the first year
- Reduce cart abandonment to below 60%
- Drive foot traffic to physical stores through app features
- Create a seamless omnichannel experience
- Establish a competitive advantage through AI-powered personalization
Our Solution
We designed and built a comprehensive AI-powered mobile shopping platform that transformed the customer experience through intelligent personalization, seamless omnichannel integration, and cutting-edge mobile features.
1. AI-Powered Personalization Engine
At the heart of the app is a sophisticated machine learning system that delivers hyper-personalized experiences:
Smart Recommendations
Collaborative filtering and deep learning models suggest products based on browsing history, purchases, and similar user behavior
Style Matching
Computer vision models analyze clothing styles and automatically suggest complementary items
Dynamic Pricing
Personalized promotions and pricing based on user loyalty, browsing patterns, and purchase probability
Predictive Notifications
ML-powered push notifications sent at optimal times with relevant product suggestions
2. Visual Search & AR Try-On
Revolutionary features that leverage computer vision and augmented reality:
- Image Recognition: Users can snap photos of clothing they like and find similar items instantly
- Virtual Try-On: AR technology lets customers virtually try on clothes, accessories, and makeup
- Size Recommendation: ML model predicts optimal size based on previous purchases and returns
- Color Matching: AI identifies colors in photos and finds matching or complementary products
3. Omnichannel Integration
Seamless connection between online and physical retail experiences:
- Real-Time Inventory: See which nearby stores have items in stock
- Reserve & Collect: Reserve items online and pick up in-store within 2 hours
- In-Store Mode: Scan items in physical stores to see reviews, sizes, and recommendations
- Store Navigation: Indoor mapping guides customers to products in physical stores
- Unified Cart: Start shopping on mobile, continue in-store, complete purchase anywhere
4. Frictionless Checkout
Optimized checkout process that dramatically reduced cart abandonment:

Key Learnings & Best Practices
This project taught us valuable lessons about building successful AI-powered mobile commerce apps:
1. Personalization is the Ultimate Differentiator
Generic shopping experiences can't compete with AI-powered personalization. Users spent 4x longer in the app and converted at 3.8x higher rates when they received personalized recommendations, proving that AI-driven customization is essential for modern retail.
2. Visual Features Drive Engagement
Visual search and AR try-on became the most-loved features, used by 67% of active users. Customers who used visual features had 92% higher conversion rates and 2.1x larger cart sizes, demonstrating the power of visual commerce.
3. Omnichannel Integration is Critical
Connecting online and offline experiences created a virtuous cycle—app users visited stores 30% more often, and in-store customers became app users. The "reserve & collect" feature alone drove $3.2M in additional revenue by combining online discovery with in-store pickup.
4. Frictionless Checkout is Non-Negotiable
Reducing checkout from 7 steps to 3 steps (with one-tap payment) cut cart abandonment by 42%. Every additional step or form field costs conversions—simplicity is paramount.
5. Start Simple, Iterate Fast
We launched with core features in week 10 and used real user data to continuously improve. The recommendation engine's accuracy improved from 72% to 89% over 6 months through iterative refinement based on actual user behavior.
Future Enhancements
Based on the app's success, the client has commissioned Phase 2 features:
