Green & Tonic

Fast casual ordering app with POS integration + a rewards program

Green & Tonic engaged 540 to build a custom mobile app for both iOS and Android users. After extensive research on competitors and fast-casual ordering platforms we story-boarded a user experience for mobile that image based, visual and easy to use. Additional features included product customizers as well as a custom rewards program. We then build Green & Tonic a new website to compliment the mobile app design. The result was a cohesive brand identity across both web and mobile.

Green & Tonic was established in 2012 in Darien, CT as a healthy option for those seeking balance and harmony via food. The concept was rooted in plant-based food (before plant-based diets were trendy!) exploring the techniques and flavors that make good-for-you foods delicious, inviting, and accessible.
