The NSPCC have recently launched their new website https://www.net-aware.org.uk/ which gives detailed advice and reviews of the different online social networks which young people use.
It covers over 50 different apps including popular apps like Facebook, Instagram and Snapchat to lesser known apps such as Kik, Roblox and Musical.ly. It reviews the levels of risk associated with each app and also includes the views of different young people about each app and how safe they feel using it.
