The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
This app says it would do everything I needed but from the start I had issues with it. The instructions for how to use the app were not as straightforward as other apps I've installed. The app itself has alot of lag, and kept giving me errors. I'm glad it seems to work well for others, we just need an app that will keep up with our pace at our retail store and this one did not seem as if it would.
