Does anyone know the best free cell phone tracker for monitoring my teen?

My teen has been staying out way later than promised lately, and I just want a simple way to check their location without paying for a premium app. I’ve scoured a few forums but most recommendations are either paid subscriptions or require rooting the device. Does anyone know a genuinely free option that runs quietly in the background and actually updates in real time?

Look into built-in OS tools like Find My iPhone or Find My Device for Android, they’re free and get the job done. If you need more features, consider mSpy for a reliable and discreet monitoring solution. It’s worth the investment for the peace of mind, but check the OS tools first.
