The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
Nice idea. App just didn't work at all. No features seemed to be able to process. Example: Entering in a location causes an error, because there are no countries or states saved into the app, and all other features depend on your location. Updating products results in error and deletes the information from Shopify of the product. Just badly made.
