Stud Alert est née d’un besoin concret observé dans les campus universitaires : les étudiants et personnels perdent souvent des objets, rencontrent des difficultés de stationnement, et recherchent des solutions simples pour organiser du covoiturage entre collègues ou camarades. L’objectif de Stud Alert est donc de simplifier la vie universitaire en regroupant plusieurs services pratiques dans une seule application.
