Jimmy John’s Mobile App Development

Industry

Food & Beverage

Jimmy John’s partnered with Detroit Labs to launch their first native mobile apps—designed for speed, simplicity, and scale. Over the years, we’ve expanded the experience with rewards, voice ordering, wearable support, and more—now serving millions of active users.

Jimmy John’s, a fast-growing sandwich chain with more than 2,600 locations, needed a mobile experience that matched its “Freaky Fast” brand promise. They turned to Detroit Labs for strategy, design, and native app development to deliver on that vision.

The Challenge

Before partnering with Detroit Labs, Jimmy John’s had no mobile presence—putting them at risk of falling behind digital-first competitors. Customers increasingly expected fast, seamless ordering from their phones. To stay competitive, Jimmy John’s needed native apps that were fast, reliable, and scalable, with built-in loyalty and personalization.

The Vision

The goal was to create a mobile experience as effortless as ordering in-store. Detroit Labs aimed to build an intuitive design, speed-focused flows, and everyday conveniences like curbside pickup, voice ordering, and Apple Watch support.

The Process

We began by mapping core ordering flows and building quick prototypes to test assumptions early. Research combined competitive analysis, user interviews, and internal feedback to uncover what mattered most to customers—and what would keep them coming back. On the design side, we created a visual system anchored in the brand’s bold color palette and typography, simplifying key screens to prioritize clarity and speed. Our native iOS and Android teams worked in tandem to optimize the experience for each platform. Over time, we partnered closely with Jimmy John’s to roll out major enhancements, including Apple Watch support, Siri shortcuts, and an intuitive interface for Freaky Fast Rewards. When the company migrated its backend systems, we adapted quickly—integrating the changes with minimal disruption to users.

The Solution

The result is a fast, reliable, and user-friendly mobile app that continues to evolve with the brand. Customers can place an order in just a few taps, track delivery, and earn rewards with ease. Since launch, we’ve continuously improved the experience—making it easier to order quickly, redeem points, and stay connected, whether through curbside pickup, Siri voice shortcuts, or Apple Watch interactions.

The app has surpassed 5 million downloads on Android with a 4.8-star rating, and holds a 4.9-star average from over 1.5 million iOS reviews. In early 2023, downloads surged 40% year-over-year—well ahead of industry benchmarks. With mobile ordering now accounting for roughly 60% of digital restaurant orders, Jimmy John’s remains a standout among quick-service brands.

Detroit Labs continues to maintain and enhance the mobile app today—scaling the infrastructure, adapting to platform updates, and delivering new features that keep pace with evolving customer expectations. The app now plays a central role in how Jimmy John’s connects with its customers—fueling loyalty, frequent reorders, and a digital experience that reflects the brand’s fast, no-frills ethos.
