Introduction
In today’s fast-paced world, managing food efficiently has become both a practical necessity and an environmental responsibility. Food waste continues to be a major global issue, with approximately one-third of all food produced worldwide lost or wasted annually. A significant portion of this waste results from expired or spoiled food in households.
Digital solutions, particularly mobile applications, have emerged to address this challenge. Apps that track food shelf life and expiration dates not only help reduce waste but also promote cost efficiency, healthier eating habits, and better meal planning.
