Photos: 3 Nigerian girls living in Ireland win an international tech competition

A group of Nigerian girls living in Ireland have won an international tech competition with an app that helps people with dementia.

Three teens took first place in Technovation Girls, a contest challenging young women and families to use technology to address real-world problems. Their app, Memory Haven, was on one of 16 finalists at the Technovation World Summit, taking the senior girl's division and being named People's Choice. 

In all, nearly 2,000 entrants from more than 60 countries entered the competition. Memory Haven has a half-dozen features targeting memory loss and speech and recognition problems - all of which are key issues faced by people with dementia. 

Photo albums allow users to view tagged photos and identify who is in the image, while a reminder feature alerts both patients and caregivers when its time for medication.
