The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
I really thought this app was unique, but after more research, there are far better apps that allow you to create multiple wishlists AND add the same product to those wishlists. (Although this app says that's possible in the description, it's not, and when I notified the developer that it wasn't working, they said it wasn't available. The fact that they still leave this in their description seems deceptive.) Also, this app is very slow to load, 1.5s according to my speed tests. We've moved on to Wishl- load times are under a second.
