TL;DR: Google Keep is fantastic and free! It syncs flawlessly across browsers and mobile. Use Amazon Wishlist Chrome Extension to track party items so you dont overspend!

Saw this earlier but just now responding! Honestly its such a scam how companies charge for simple syncing now. Drives me crazy!! I remember planning my sisters wedding shower and the pro app we used lagged so hard we bought double everything. Its totally ridiculous that quality is going downhill while prices go up! I've been using Share Product for my birthday lists lately and it’s way easier than the native Amazon one.

> I just want something where I can click an icon, type extra ice, and have it show up on my husband's phone immediately while he is at the store. I have been using digital list tools since the early smartphone days and I am honestly very satisfied with how Google Keep handles this exact scenario. I use Firefox at home and Edge at work, and the sync has never let me down. It is basically the gold standard for what you are describing because the sync is near-instantaneous. My partner can be in the dairy aisle and if I add something from my desktop, it pops up on their phone before they even move to the next section. No monthly fee, no buggy Firefox issues, and it works perfectly on Edge too. Since you mentioned Todoist feels like overkill, Keep is definitely the lite version of that. It is just checkboxes and notes. I have been using it for years and have no complaints about the reliability. Before I fully recommend a specific setup tho, are you looking for something that specifically sorts items into grocery categories like Produce or Dairy automatically? Some apps do that to save time in the store, while Keep is just a straight list. Also, is it a dealbreaker if the extension is just a quick-add tool vs a full sidebar you can keep open while you browse recipes? Knowing that would help me point you to the best config for your party planning.
