App Shopping List
This App is a simple shopping list which allows you to store your items you need to buy. Recently bought items can be added to the list easily again.
You can create new lists and share these with others. In case of iPhone users they can use a safe iCloud access just to your shared list while sharing with Android users you have to use a secure service called Firebase. For this purpose they have to create an account in their app to get a verified e-Mail address for sharing the lists.
In the settings you can change the theme, a different background color or use a background image. The opacity slider allows you to improve the contrast in case you choose a light or dark image. Be sure to choose the correct theme before you pick a background image because this influences how certain texts are highlighted (dark or light background color).
