Above Android Oreo version, the voice control and language selection did not work
The program is a simple shopping list. Neither more nor less. Maybe little bit more.:)
Basically it is made for the replacement of the paper based shopping list. It handles two lists, an own list and a partner list. You can place and cancel items for/from both lists by voice recognition (in more language) and by typing. The difference is in the cancellation: you can cancel the items from the partner list only limited.
The program synchronises the lists with the program of the partner through web, so our wife can send us the shopping list even underway.:)
