Yes. Some parental apps can scan your WhatsApp messages to varying degrees. For example, parental control apps like mSpy give you full access to all of your kid’s activity on WhatsApp, including their messages, pictures, voice calls, and contacts.
But instead, I prefer apps like Bark that only show you messages that trigger its alert system. This way, you don’t have to spend hours scrolling through the app to find specific instances of concerning content, and you still get to see the messages that are potentially inappropriate. You can give Bark a try for free for 7 days to see how it monitors your child’s WhatsApp and which types of messages trigger alerts.
