What We Build

Comprehensive E-commerce Mobile Engineering

01

Native Product Catalogs

Engineering fluid product grids with instant search auto-completion, infinite scrolling, adaptive image sizing, and offline catalog caching.

02

Frictionless Single-Tap Checkout

Integrating native Apple Pay, Google Pay, and saved card profiles, allowing users to buy in seconds without filling out address fields.

03

Dynamic Cart & Pricing Engines

Building real-time discount calculations, coupon code validations, and inventory checks that sync instantly with your backend CMS or ERP.

04

Targeted Push Notifications

Setting up contextual push notification triggers for abandoned carts, price drops on favorited items, and shipping status updates.

05

Unified Analytics & User Tracking

Integrating event-based analytics (Mixpanel, Amplitude) to monitor user funnels, track drop-offs, and measure conversion lift.

06

CMS & Headless Integrations

Connecting the mobile frontend securely to Shopify, BigCommerce, WooCommerce, or custom headless engines via fast, optimized GraphQL APIs.

The Challenge

If your mobile shopping app is just a website wrapper, users will abandon their carts.

Mobile represents over 70% of online shopping traffic, yet mobile conversion rates are notoriously lower than desktop. The reason: slow page loads, clunky navigation, and complicated checkout forms on small screens. Pushing users to a responsive website or a slow app wrapper results in high bounce rates and lost revenue. To capture today's shoppers, you need a mobile application that loads catalogs instantly, supports single-tap payments (Apple Pay, Google Pay), and keeps users engaged through targeted, non-intrusive push notifications. Quecko builds native and optimized cross-platform e-commerce applications with performance budgets. We prioritize checkout speed, image caching, and localized catalog loading to deliver fluid shopping experiences.

FAQ

Frequently Asked Questions

Yes. We integrate with Shopify's Storefront API (GraphQL). This allows us to fetch live product details, variant allocations, pricing changes, and customer profiles in real-time, ensuring inventory count parity between web and mobile.

We use tokenized payment architectures (via Stripe or Adyen). The card information is encrypted directly on input and sent directly to the gateway's server. Our application database and mobile client only save a secure payment token, keeping your app compliant with PCI standards.

In a headless setup, the frontend mobile application is decoupled from the backend CMS. This allows the mobile app to communicate with lightweight database APIs directly, yielding faster catalog load speeds and more flexible UI options than standard web layouts.

We integrate push notification triggers linked to your analytics database. If a user adds an item to their cart and does not checkout within a set timeframe (e.g., 30 minutes), the system automatically triggers a personalized push alert with a call to action.
