Optimization feels a lot less optimal when it leads to enshittification. I have worked on the tech side of accounting systems in the US for the last 10 years and can say that American companies have largely embraced this category of innovation as well.
AnyList. I’ve tried many list apps and this one is easily the best. Not FOSS disclaimer. The free version has very minimal ads, it has a great, intuitive UI, you can create custom list types and item categories, it has built in quantity and unit of measure fields, and you can share/sync a list with others by email address. The amount of features included in the free version is uncommon in the market without getting more harassed by advertisements. I hope it doesn’t change in the future; it’s remained relatively unchanged for the 3 years I’ve been using it!
