The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
I use this app since 6 months and there are some things they should improve. I can't translate the word "item" below in the cart (in my case to spanish) and the app should have some system to enter the delivery/pickup hour. There's also a problem with the design of the app's page (a white container in the screen that occupies a lot of space) The rest is simple and works good. The team is working on solving this problems, I'll update this review when solved.
