If you want to scan items very quickly, you need to download the database onto your phone, which is available in Professional Plans. This will allow the app to check the price without having to access the Internet, then return the information in less than a second. When you use the database, barcode scanner, and audio cue all together, you can quickly go through the items with much less work.
To download the database to your phone, tap the menu icon (1), then select Download (2).
On the download screen, (3) is the creation time of the current database on your phone. You can choose to download the media and/or the non-media database (4). The progress bar (5) shows you the download progress, estimated time to finish, and current download speed. If it takes longer than the screen is showing here, run Google’s Internet speed test* and contact your Internet provider if your Internet speed is too slow. You can tap the Start/Stop button (6) at any time to start or stop the download. After the download finishes, tap the Close button (7) to go back to the main screen. Download status is displayed at (8).
