Claire Lilley, head of child safety online at the NSPCC, said cyber-bullying is a "huge concern".
She added: "The use of teen dating apps can expose children to contact by adults who have a sexual interest in them because the age controls are often inadequate.
However, more than three-quarters (77%) of mothers and fathers polled said they had conversations about online safety, up from 68% last year.
The sharing of “conversational turn-taking” and the ability to tune in to the other person are early indicators of relationship prospects and limitations.Users are shown other subscribers close to their location and must give a positive reaction to them in the form of a tick, and receive one back in order to start communicating.It is open to those who are 13 or older, with under-18s only able to match with people in the same age bracket.This promising connection suggests the possibility of a relationship and this triggers the emergence of fantasies and needs. The dance of flirtation may not indicate a “readiness for relationship.” These are two different things.Larger mental and emotional fantasies evolve, generating a complex landscape of relationship possibilities, both positive and negative.
