How BODi Enhanced Its Fitness and Wellness Apps

The ChallengeScaling apps for ambitious features

BODi ran several apps that let subscribers follow along with at-home workout videos for a few dollars a month, and originally brought X-Team on board to improve their performance.

The decision to add live classes, a personalized meal plan and tracker, and hundreds of workout videos meant those apps would need significant upgrades to handle the new scope.

The SolutionA cohesive cross-platform architecture

• TypeScript codebase across the apps, reducing the risk of errors and bugs and speeding up onboarding of new developers.
• React Native mobile apps let X-Teamers reuse JavaScript skills to write shared code for both iOS and Android, significantly speeding up development.
• Redux-Saga global event bus connected all of BODi's apps so teams working on different parts could understand and react to each other's work.
• Gatsby web app chosen for its performance gains, with a pre-production environment that smoke tests everything before it goes live.
• Web performance techniques from asset optimization to prefetching kept the web app running as fast as possible.

The ResultsFast, cohesive apps that scaled

Together with X-Team, BODi shipped cohesive, fast applications with great UX — Mashable named the Openfit app the best app for real-time feedback. The web app grew rapidly, quickly hitting 100,000 subscribers.

X-Team developers worked on the app's checkout, and users reported virtually no issues at launch, giving BODi a steady stream of income from the web app without technical hiccups. The two teams continue to make the app faster and more streamlined, which users regularly note in reviews.
