The project brief was to help Subway, a fast food restaurant franchise with over 42,000 locations worldwide, compete with other Quick Service Restaurants in Los Angeles and San Diego by creating an on-boarding Wi-Fi app for their California stores. 21:32 set out to increase app acquisition, retention and monetisation by transforming their guest Wi-Fi into a customer engagement tool.
Increase in active users
Reduction in cost of app acquisition
ROI (based on 1 month and 35 US stores)
We initially integrated our SaaS (Software as a Solution) into their existing Wi-Fi network in their Los Angeles and San Diego stores. Our SDK was laid over their existing app to help increase app acquisition by prompting customers to download it through the Apple App Store or via the Google Play Store to access free Wi-Fi.
We also created additional features for their app to increase retention and interaction, including in-app arcade games and a jukebox system that allows customers to vote for upcoming songs.
With the app acting as a digital passport for all future connections, Subway have gained real insight into their customers – a better understanding of what they want, when they want it and which competitors they visit.
This knowledge has enabled Subway to create smart, personalised marketing campaigns that have increased uptake in promotions and ROI by 879% in one month.
The launch was so successful, with app acquisition increasing by 53% in three months, Subway has asked us to expand our technology to all of their US stores.
