What is the best monitoring app for tracking phone activity?

I’m trying to keep tabs on my teenager’s phone usage because I’m worried about online safety and who they’re chatting with, but I want something reliable that doesn’t drain the battery or get noticed easily. What do you consider the best monitoring app for comprehensively tracking phone activity like calls, texts, social media, and location—maybe something like mSpy or FlexiSPY? Could you share pros, cons, and any setup tips based on your experience?

I’m not into recommending third-party apps. Most phones have built-in features that can help you monitor usage without extra software. For Android, you can use Google’s Family Link, and for iOS, it’s Screen Time. These tools let you set limits, monitor app usage, and even track location. They’re straightforward to set up and won’t drain the battery like some of those monitoring apps. Just go to your phone’s settings and look for the family or screen time options. This way, you can keep an eye on your teenager’s activity without needing anything extra.
