<p>Workplaces are potentially effective settings for promoting mental health. Changes to working styles from the pandemic offer opportunities for organizations to rethink traditional approaches to improve mental health in the workplaces. This includes digital health platforms with the capability to deliver information, resources and interventions at scale across the mental health continuum. This study explored the desired features of a workplace mental health app and potential drivers or barriers to adoption. Twenty-three participants aged 21–63&#xa0;years working in Singapore were recruited for semi-structured interviews. A reflexive thematic analysis was used to extract constructs and themes from the data. Participants felt mental health apps increased accessibility to mental health services and reduced stigma towards help-seeking. Participants desired self-help features like educational content, reminders, social features like gamified challenges and online communities. Potential drivers of app adoption include incentives, timely and relevant campaigns, good user experience and the ability to integrate with existing platforms that users were familiar with. Potential barriers included data privacy and cost. Some participants preferred alternative coping strategies like social media over using mental health apps. Mental health apps could play a role in workplace mental health promotion. Self-help and social features are key elements desired by participants. Organizations could provide incentives and a good user experience for employees to promote app adoption while communicating transparency on data privacy policies.</p>
