About

AADJ

Features
Read full description

AADJ is a national nonprofit organization dedicated to advancing equity and inclusion for individuals with disabilities, caregivers, and families by connecting them with care, community, and practical support. Our member app extends this mission by turning those supports into everyday tools that live on your phone, so existing members can more easily manage their health and access information when and where they need it. Within the app, members can book and attend virtual physician visits, allowing them to connect with healthcare providers from home or on the go. These visits are designed for routine care, follow-ups, and non-emergency concerns, helping reduce transportation challenges, time away from work or caregiving, and the stress of in-person waiting rooms. The scheduling flow is simple, so users can see available appointment times and confirm visits in just a few taps. The app also includes a digital pharmacy card that members can show at participating pharmacies to unlock prescription savings. Instead of carrying a separate card, the information is stored securely in the app, making it easy to access at the pharmacy counter. This feature helps lower out-of-pocket costs for medications, which can be especially important for families managing multiple prescriptions or ongoing treatment plans. In addition, a dedicated resources section offers curated articles, guides, and updates created with individuals with disabilities, caregivers, and families in mind. Topics may include navigating benefits, understanding rights and accommodations, caregiving tips, mental health and wellness, and news relevant to disability communities. Content is written to be practical and easy to understand, so members can quickly find clear, actionable information and return to it whenever needed. Together, these features help the AADJ app serve as a practical companion to membership, supporting users’ health, and everyday decision-making in one accessible place.
