As far as the reviews of the apps
, Kendall leads with four stars. That being said, ET points out
that while Kylie's app may only have a 3-star rating, it has been reviewed at least twice as many times as all of her sisters, combined. That's over 800 ratings! Of those, she has more than 300 5-star reviews, which is, again, more than Kim, Khloe and Kendall, combined.
