Very safe for kids! It isnt all for girls either, there are many boy characters to unlock. It also doesnt have lag, which most games have an issue with. I just have a few complaints. Alot of the stuff costs alot of coins. I know you are supposed to earn it, but it is still over 2,000 coins to get a single decal! Though there are boy characters, there is still alot of pink and purple. How about some green or red? That is my review on this app! Hope it was helpful!
