About Bodybuilding Warehouse
Bodybuilding Warehouse (BBW) is one of the UK’s most established sports nutrition and supplements retailers, serving fitness enthusiasts, professional athletes, and everyday gym-goers for over a decade. With a catalog that spans hundreds of products, from creatine and protein powders to amino acids, vitamins, snacks, and goal-based supplements, BBW has built its reputation around quality, affordability, and trust.
What sets BBW apart is its dual identity: not only does it carry leading third-party brands, but it also manufactures its own in-house supplement ranges, ensuring variety and value for customers. This made the brand a go-to choice for consumers looking to fuel their health and fitness journeys.
But while the product strategy was strong, BBW knew that customer expectations were shifting. Increasingly, shoppers were moving away from desktop and mobile web, seeking faster, more engaging, and seamless app experiences. To stay ahead, BBW realized its digital infrastructure had to evolve too.
Moving Beyond an Underperforming App
Before working with Appbrew, BBW already had an app in place with Tapcart. However, it fell short in several ways, creating friction rather than acting as a growth driver.
Limited Usability and Performance
The existing app struggled to deliver the speed and polish customers expected. Navigation was clunky, load times were slow, and the overall experience didn’t feel like a natural extension of BBW’s website or brand. Customers came to browse but didn’t stay long enough to convert.
Conversion Bottlenecks
Despite strong mobile traffic, the app wasn’t converting at scale. With conversion rates lagging behind the brand’s ambitions, the app wasn’t tapping into the full potential of BBW’s mobile-first audience.
Low Engagement and Discovery
Engagement times remained shallow compared to industry benchmarks. The catalog, though broad and diverse, wasn’t being surfaced in a way that encouraged exploration. Without a discovery-led experience, shoppers missed opportunities to build larger baskets or find new products.
Integration Gaps
BBW wanted its app to fit seamlessly into its broader marketing and retention stack, powering loyalty flows and personalized campaigns. But the old app offered limited integration flexibility, making it harder to execute targeted, impactful campaigns.
BBW’s leadership knew they weren’t just looking to tweak their existing app. They needed to reimagine the app as a performance-first growth engine, one that could drive conversions, boost engagement, and contribute meaningfully to overall revenue.
A Mobile-First Growth Engine
BBW partnered with Appbrew to rebuild its app from the ground up, not just as a storefront but as a digital channel designed for scale, loyalty, and growth.
Appbrew’s approach focused on three pillars: performance, conversion, and engagement.
Performance-First Design
Appbrew delivered a fast, reliable, and visually aligned mobile app that mirrored BBW’s brand identity while elevating usability. With smooth navigation, optimized product feeds, and quick-loading pages, the app provided the kind of mobile-first experience modern shoppers expect.

Conversion-Centric Journeys
The app was built to optimize every stage of the funnel. Upsell and cross-sell prompts were embedded across PDPs, carts, and collections, while curated sections like “Top 20 Products” and “Shop by Goals” guided customers toward high-value discoveries. This turned passive browsing into purposeful shopping.

Deeper Engagement Through Discovery
Appbrew reimagined how customers explored BBW’s catalog. Instead of static lists, the app offered curated collections and goal-driven shopping with categories like “Build Muscle” or “Fat Loss”, echoing the kind of guidance a personal trainer or nutrition coach might give. This encouraged customers to spend more time exploring products, leading to longer sessions and more repeat visits.

Seamless Integrations for Retention
By providing access to integrations, Appbrew gave BBW the tools to plug its app into the broader retention ecosystem. This enabled personalized campaigns, loyalty flows, and targeted messaging that strengthened customer relationships beyond the first purchase.
The Results: Mobile as a Growth Driver
The impact of Appbrew’s partnership was immediate and measurable:
- 2x Higher Conversions
The app conversion rate nearly doubled compared to the website, proving that smoother journeys and better flows directly translated into more purchases. - 50% Higher AOV
Customers spent significantly more per order on the app than on the website, a result of features like cross-sells, upsells, and curated bundles that encouraged larger baskets. - 8x More Engagement
App users spent eight times longer on the app than on the website, creating space for richer discovery and multiple interactions across categories. - 18% Revenue Contribution from App
Within the first few weeks of launch, the app scaled to contribute nearly a fifth of total revenue, cementing itself as a cornerstone of BBW’s digital strategy.
Why Bodybuilding Warehouse Chose Appbrew
BBW’s decision to switch to Appbrew was rooted in more than just technology. They wanted a partner who could help them unlock the full potential of their mobile channel. Appbrew stood out for:
- High-performance mobile experiences that matched the speed and scale of BBW’s ambitions.
- Seamless integration capabilities, allowing BBW to connect their app with retention and marketing tools effortlessly.
- Conversion-driven design, with upsells, cross-sells, and curated browsing built into every journey.
- Dedicated support and guidance, ensuring a smooth transition from the old app while providing proactive strategies to scale the new app as a core growth driver.
Appbrew didn’t just give Bodybuilding Warehouse a new app. It gave them a mobile-first platform for growth, turning an underperforming channel into a central driver of revenue, engagement, and long-term customer loyalty.
