"In cities like Milan, student dorms and shared apartments offered a chance to observe how groceries are consumed in fast-paced environments, and whether (and how), they’re shared among people with different relationships."

Introduction
Tracknshare is a connected system designed to support consumers in planning meals and food purchases, with the goal of minimizing food waste. Originally envisioned for student households and shared apartments, Tracknshare’s concept is simple: make it easier to track what you buy, use what you already have, and share what you won’t. Thanks to RFID and computer vision, Tracknshare can register products purchased at the supermarket when placed in a dedicated tote bag (a working prototype was built) and compare them with items already at home, detecting duplicates or suggesting combinations. At home, users are notified when products are nearing expiration and can choose to share them with nearby users, turning potential waste into shared value. As an academic team project, the idea was originally inspired by our personal experiences living away from our families, with some of us struggling to reduce food waste/finding ways to connect with neighboring student households.
Research insights
We conducted a survey to explore the food purchasing and consumption habits of students from our university and others in Milan. Along the way, we ended up including a broader pool of potential users, mainly workers in the 25-35 age range sharing accommodations with students. We asked about their habits and routines to find out what a typical day in their life looked like. A clear pattern quickly emerged as many of them were facing the same nutrition-related challenges:
Frequent grocery trips with small purchases, often due to not having a car to enable less frequent but more intentional shopping.
Regular online food delivery orders.
Busy schedules that left little time to go home and plan meals before grocery shopping.
Without family responsibilities, many skipped meals or ate out instead.
In households with pre-set rules like “everyone eats their own food,” people were often reluctant to share.
Diverse backgrounds resulted in different tastes and eating habits.
Relationships with neighbors were often minimal or non-existent, making food sharing a new and unfamiliar concept.
The kit
We developed a system that combines established technologies like RFID scanning with the advancements of computer vision. The standard product includes a kit with a SmarTote, one or two cameras, and the app. The cost could be split between the household components or purchased upfront by homeowners as an added service in the lease. In the event of a commercial launch, the app would remain free to use without requiring the full kit; users could simply add and remove products manually.
The app
My contribution to the project included the and the development of Tracknshare's app (frames 1-1c, 2, 5-5b) along with its design language (frames 7-7f). The frames illustrate how users navigate the app’s sections, easily access and manage the broader Tracknshare system, and move smoothly between tracking and sharing modes.
Conclusion
Tracknshare was built around a simple idea: reducing food waste starts with knowing what we have, what we need, and what we can share. By combining smart tracking with thoughtful design, the system supports more mindful habits in everyday life, especially in shared homes, where coordination is key. Whether it’s avoiding duplicate purchases, using ingredients before they expire, or offering them to others nearby, Tracknshare turns routine actions into opportunities to waste less and connect more.
