Is there a good family monitoring app for tracking teens?

My teenager has been staying out way past curfew and I’m getting really worried about their safety, but they get super defensive whenever I bring up tracking. I’ve looked into a few options but most seem either too expensive or just creepy to install without them knowing. Any recommendations for something discreet that actually works well and doesn’t drain their battery?
