Why does the application need to download 20Mb of data during installation?
One of the unique features of Ocado on the Go is that you can perform a complete shop to the point of checkout if offline. To do this, the app downloads our complete catalogue of 21,000+ products, which is then kept up to date in the background as you shop. An additional benefit of storing the catalogue locally is that, unlike conventional web applications, the speed of shopping does not drop in areas of poor reception.
