Should be easy to use, remember what I bought before and propose things that are probably running out (based on my personal buying frequency), and allow sharing the list between multiple people. Ideally also allow adding recipes for meals that I cook often.
What I wish existed was a self-hosted version of OurGroceries.
If you want self hosted, I’d second all the Grocy comments. I don’t use it because it isn’t simple enough for my family, but I did like it.
I love OurGroceries!!! It’s so handy. ngl…the app would be worth an annual subscription and makes me wonder how they keep their app running with just a one-time payment.
