What's a good Android app for, like, scaring my little cousins into behaving when they're over?

Alright, so I stumbled upon this app called شرطة الأطفال - مكالمة وهمية, and it's pretty straightforward. It's basically a simulated phone call from the police. The idea is to, uh, encourage better behavior in kids. I know, I know, it's not exactly cutting-edge tech, but judging from the reviews, some parents swear by it. From a technical standpoint, it's super simple – probably built with, like, basic Android SDK stuff. I'm guessing the dev team really thought about ease of use over fancy features, which, honestly, is probably the right call for this kind of thing. It's got a 4.1 rating, so it's not terrible. Just, uh, use it responsibly, alright? No more spaghetti code situations in your parenting!
