There are people who are hired specifically to pad reviews. They're easy to spot though. Every 5 star review reads exactly the same even if it's different wording.
"This app changed my life!"
"I was looking for so long to have an app like this so I'm happy this app exists!"
"This app is so easy to use and install, I don't understand why people are complaining about it"
