What's a good Android app for chatting with people, but also letting me filter by age? You know, keep things appropriate... like setting up study groups, not... well, you know.

So, I was looking for a way to maybe connect some of my students for study groups outside of class, and my student, Sarah, suggested I try this 'Wizz App' thing. I'm not the most tech-savvy guy, took me a few days to figure out all the features. But it's surprisingly intuitive, even I could figure it out. The best part is that it lets you filter by age. I can set it so that the kids are only chatting with others in their grade. It's like having a teaching assistant in your pocket, making sure everyone's where they should be. Now, I know what you're thinking – 'Mr. Thompson on a chat app?' But honestly, it's been useful. I just wish they made the settings a little easier to find; why do they hide the settings button there? Still, once you get the hang of it, it's not bad for keeping an eye on things.
