ZenCart
How we built a Flutter e-commerce app with AI-powered product discovery, Stripe Checkout, Apple Pay, and Google Pay — delivering a 185% higher conversion rate than the client's legacy native app.
“We went from a 2.1-star app to a 4.9-star app in a single release. The Flutter rebuild with proper Stripe flows completely changed how our customers feel about buying from us.”
— CTO, ZenCart
The Challenge
A slow, buggy native app with a broken checkout drove customers to competitors and dragged down the brand's reputation.
Cart Abandonment Crisis
The legacy iOS app had a 5-step checkout process with no saved cards and no Apple Pay — 81% of users dropped off before completing a purchase.
iOS-Only, Slow & Buggy
Maintaining two separate codebases (Swift + Java) was consuming 80% of the dev budget, leaving no resources for features — Android users had been abandoned for 18 months.
The Flutter Rebuild
We rebuilt the entire app in Flutter with a single codebase, AI recommendations, and a one-tap Stripe checkout with Apple Pay and Google Pay.
Stripe Payment Sheet
Integrated Stripe's Flutter SDK with Payment Sheet — one-tap checkout supporting cards, Apple Pay, Google Pay, and saved payment methods with 3DS2 authentication.
AI Product Discovery
Built a personalized recommendation engine that surfaces products based on browsing behaviour, increasing average order value by 67% through intelligent upselling.
Cross-Platform in One Codebase
A single Flutter codebase ships pixel-perfect experiences on iOS and Android, cutting development costs by 55% and halving release cycle times.

Impact
ZenCart's rebirth on Flutter with Stripe turned a failing app into the client's primary revenue channel within 90 days of launch.
81% → 23% Cart Abandonment
One-tap Stripe checkout with Apple Pay eliminated the friction that was killing conversions — users now complete purchases in under 8 seconds.
55% Reduction in Development Cost
A unified Flutter codebase replaced two separate native teams, freeing budget to ship 3x more features in the same time.
One App. Every Platform.
ZenCart proves that Flutter done right isn't a compromise — it's a competitive advantage that ships faster, costs less, and converts better than anything that came before it.
