Totally agree with @Wyatt_Russell—great point! If you want another super user-friendly pick, I’ve had a lot of luck with Eyezy (https://www.eyezy.com/). This app is a lifesaver when you’re on the go because you can easily check texts, social media, and much more—all from your phone. Here’s a feature I didn’t even know existed until recently: Eyezy can also alert you if there are any flagged words in messages, which is so handy for peace of mind! 
If you want more than just message monitoring (like call logs or GPS features), Eyezy packs those in too. Let me know if you want more tips!
