Lidl PLU Ireland and Northern Ireland is an app to learn the PLU numbers of non-scannable items anywhere and at any time. The app was developed to allow PLU employees to view the prices of the products instantly, especially during checkout. 

The app has two modes: the learning mode and the training mode. In the learning mode, you will learn the product names and their corresponding PLU number. In the training mode, on the other hand, you have already memorized them as you will need to put them into practice by then. 

The training mode consists of games where you will be asked to identify the product shown on the screen with six possible answers. You will also need to identify their correct PLU numbers. This game aims to check your learning progress
