Case Study: GNC launches a headless mobile commerce app on fabric and lifts mobile revenue 55%
Key results
The challenge
GNC, the health and wellness retailer, needed to rebuild its mobile e-commerce app under a strict deadline in a growing category. A full replatform would have been too slow, so GNC needed to reuse its existing systems and code to reach market quickly.
The solution
GNC worked with fabric to deliver the app through a phased, highly segmented release schedule that integrated GNC's existing systems and repurposed code. fabric built the app from three components — a fabric Storefront, fabric XM middleware that lets the business team push daily UI updates, and supporting services — and added payment options including Apple Pay and PayPal.
The results, in context
fabric developed a fully functional app in 12 weeks and launched it on time. Following launch, GNC reported a 55% year-over-year increase in mobile revenue, a 23% improvement in incremental revenue since launch, and a 75% reduction in the app's crash rate versus its previous app, with metrics recording more than 20,000 concurrent users by January 2022.
