Yubo is a popular mobile app that lets users create a profile, with photos and videos, and swipe through other profiles of users in their local area. If they match, they can then chat.
Thinkuknow - the education programme of The National Crime Agency’s child protection command CEOP - has created a guide for parents on how the app works and what your child needs to know about how to use it safely.
Update January 2018
Yubo is the new name for the app Yellow. The app also now has a live group video chat feature.
