How Can I Monitor Kik Messenger On My Child'S Phone?

I’ve been getting increasingly worried about my child’s activity on Kik Messenger, especially since I’ve heard it’s popular among strangers trying to contact kids. I’d like to find a reliable way to monitor their Kik conversations, including any media they send or receive. Are there any parental control apps that let me see their Kik chats in real time, and would my child be able to tell that the monitoring is active? I want to keep them safe without completely breaking their trust.
