A new app for dementia patients, called Memory Haven, is coming to app stores. But this app wasn’t created by professional developers— it was designed by three Nigerian Irish teens. Rachael Akano, 16, Margaret Akano, 17, and Joy Njekwe, 17, were inspired to build Memory Haven by their mentor, Evelyn Nomayo. Nomayo’s mom had experienced dementia, a disease that affects cognitive abilities. The friends worked together to determine what tools dementia patients might need, and ultimately settled on six different features, including a mood tracker, reminders, and music to trigger memories. The app went on to win first place at the Technovation Girls international championship, a feat the team hopes will help encourage more representation of women and people of color in the male-dominated field. “I hope that with the shift toward diversity . . . people will no longer feel out of place,” Joy says, “because there really is a place for everyone in the tech industry.”
