Really? I only used the recipe book once but it seemed easy to hit the checkboxes and move ingredients over to my grocery list.
Mostly I just use it to sync shopping lists between myself and my partner. For that it has been quite reliable. Yeah I can imagine some UI improvements, but overall I think it’s pretty good.
Can you find a better grocery app? I’ve tried a ton of them and most were horrible. Either they had a hard-to-navigate UI with no dark mode, or they didn’t allow syncing with another person, or some major functional problem.
There used to be a grocery app I loved called Cinnamon but the dev stopped maintaining it :(
