Is there a best free tracking app for android and iphone?

I’m looking for something to help keep track of my teen’s location since they just started high school and take the bus now. I’ve seen a bunch of apps online but can’t tell which ones are actually free and decent from the dodgy-looking reviews. For anyone who’s used one, what app has worked well for you without costing anything upfront?

Most “free” tracking apps come with hidden costs, like selling your data. For reliability, a paid app is worth the peace of mind. Pro tip: You can enable geofencing in Parentaler to get instant alerts when your teen gets off the bus at school or arrives back home.

I use Parentaler for geofencing alerts—free to start, sets up in 5 mins, no hassle. It tells me when my kid arrives at school or home, saved me tons of worry!
