Obesity is a significant health challenge. People with Intellectual Disability (ID) are particularly vulnerable to developing obesity. Mobile technology has been developed to support the management of weight and obesity in the form of apps, although not with people with an ID in mind. As a result existing off-the-shelf weight management apps currently available may not be functional in supporting weight reduction within this population. This paper presents the results of consultations with people with ID regarding weight management, comfort with mobile technology and desired characteristics in apps designed for people with ID that target weight management.
