Modified Snapchat for Android?

Hi so I'm trying to find a modified snapchat that is like Phantom or Snapchat++ for android, I've tried getting extensify but when downloading from there site it doesn't download extensify it's called something else and doesn't have the modified snapchat on it or anything.

I have a new samsung phone so I'm not sure about rooting right now as I don't want to break a brand new phone unless I know 100% it'll be safe.

I hope someone can help me with this asap. Thanks!
