Featured Case Study

Admiral Sports Shop

BUYTE built a Progressive Web App and native iOS and Android apps for Admiral Sports Shop, a Greek sports retailer trading as Diethnis Athlitiki. The project combined an offline-ready PWA, a store locator with in-store pickup, and app-store distribution on one design system. The result: 50% faster load times, a 30% increase in conversions, and 40% higher mobile engagement.

Objective

Admiral Sports Shop needed one fast, mobile-first shopping experience instead of a slow website and a separate, disconnected app. Sports shoppers browse on the move, often on patchy connections between matches, gyms, and stores, so every extra second of load time cost the business a sale.
Three problems shaped the brief:
  • Mobile speed. The existing site was not built for how sports shoppers actually browse: quickly, on a phone, often between other activities.
  • Two channels, one budget. Building and maintaining a website and a native app as separate projects doubles the design, development, and update effort.
  • Online and in-store disconnect. Customers who wanted to check stock or pick up in person had no bridge between the website and the physical shop.
BUYTE’s brief was to solve all three with a single platform: a Progressive Web App (PWA) as the foundation, paired with downloadable native apps for iOS and Android for customers who wanted a permanent home-screen presence.

Define Goals

The PWA is the core of the platform. It loads fast, keeps working with a weak or no connection, and runs the same experience on any device without an app-store download. For a sports retailer, that means a customer can keep browsing a product page in a stadium, a gym, or the subway, and pick up where they left off once they are back online.

Alongside the PWA, BUYTE built downloadable native apps for iOS and Android. These give returning customers a permanent icon on their home screen, deeper access to device features, and the native app-like feel that habitual shoppers expect from a retail brand they use often.

The platform includes a store locator tied to a store pickup feature, so a customer can order online and collect in person. This turns the app into a bridge between digital browsing and the physical shop rather than a competing channel.

The interface strips away distraction: clean layouts, clear product hierarchy, and short paths from browsing to checkout. Fewer visual obstacles between a shopper and the buy button is one of the simplest, most reliable ways to lift conversion rate on a retail platform.

BUYTE built the front end from reusable, adjustable components rather than one-off page layouts. That lets the Admiral Sports Shop team update promotions, swap seasonal campaigns, and refresh sections quickly, without a developer rebuilding the page from scratch each time.

Result

The new PWA and mobile apps delivered measurable gains across speed, conversion, and engagement:
  • 50% faster load times. Optimized caching and a leaner front end cut load times roughly in half, directly improving the shopping experience.
  • 30% increase in conversions. Faster navigation and a shorter path to checkout translated speed into sales.
  • 40% higher mobile engagement. Customers spent more time browsing across the PWA and native apps combined.
  • Stronger customer satisfaction. A consistent, smooth experience across web and app increased loyalty and repeat visits.
These are the kind of gains that show up consistently across retail PWA projects industry-wide. Google’s own web.dev PWA documentation and independent case-study trackers report similarly large swings, retailers moving to a PWA commonly see conversion increases in the double digits and load-time cuts of a similar scale to what Admiral Sports Shop achieved, because speed and installability remove the two biggest points of friction in mobile shopping.
