Classmates is a social networking application designed to help users reconnect with former schoolmates. Launched in 1995, it provides a platform for users to find their classmates, create profiles, and share updates. Features include the ability to search for members by name, view and post photos, and maintain an updated profile with personal information such as location and birthday. Users can also join multiple school affiliations if they attended more than one high school.

The app allows users to explore Class Lists to see how many members are associated with their school, making it easier to reconnect with friends from the past. The photo-sharing feature enables users to reminisce by sharing memories from their school days alongside current updates. Classmates is available for free on Android, making it accessible for anyone looking to reconnect with their past.
