kudos! i got similar problems with optimizing recipes & groceries, but i never got past google keep and apple reminder.

anyway, a word of caution about open sourcing. people are quick to scream that you make the source available. but what about this? an article/blog describing in more details how you solved the problem instead? few people ever ask that.

what i saw with open source is, once you put the code out there, people will start requesting features, making you carry the burden of maintenance, etc. but ofc there are good things too. i just haven't seen it with small niche projects.

my 2 cents.
