I LOVE Roblox.If you are looking for an app with multiple things to do,this is in 1st place for me.If your kids are underage a thing you can do is get their profile on your device so you can see if they are doing anything you do not approve of,you can tell them that you don't want them doing whatever it is they are doing that upsets you.I think this is an amazing app for if you are trying to make friends or are trying to communicate with people you already know.You can customize your avatar to look like you or to make it look like something or someone random,you can make your avatar better if you buy robux. Speaking of that,my only complaint is that you can't buy more than 800 at one time,and the least you can buy at a time is 80,one more thing that I would count with the robux is how it isn't easy to donate robux,I want to donate my niece some,but i can't figure out how to get them to her.You can also create your own games and clothes also.
