Bests & Worsts Reviews from Amazon

This is a very great app, I love it! Also by the way I'm the kid giving the Review. There are a few problems I have with this app though, Im on a fire 8 and my friend is on a phone so when I text my friend he answers my texts like 2 minutes after I text him, me well its more like 30 minutes when I answer his texts, so that probably means he gets Notifications and I dont, fix that plz. And also one of my other friends has this app but when he clicks on it it dose not let him in we don't know why! Other then that it is a great app!
