Those social ex­clusions, manifested as the digital divide and access inequality, are further exacerbated by limited resources and lacking guidance for urban technology usage. Taking the COVID-19 pandemic as an example, where the usage of contact tracing applications became mandatory in Hong Kong, it was evident that citizens without access to these services faced restrictions on their movements, impacting their travel habits. This underlines the assumption that smartphone ownership is a basic human right to access digital services. This paper, using the post-pandemic period in Hong Kong as a case study, aims to investigate gendered differences in the usage of smartphone-based mobility services(SBMS). Through a territory-wide survey in 2023, along with expert and in-depth interviews, this paper reveals gendered differences encompassing types of SBMS, financial ac­cessibility, daily travel routines, and encountered problems. This paper also delves into gendered attitudes towards smart mobility, revealing nuanced negativity across different aspects. These findings emphasize the importance of considering gendered differences when promoting digital mobility services as the primary option for future urban development initiatives .
