Ive been the designated family gift coordinator for like ten years using a basic Google Sheet but things are falling apart this year. My family has grown so much with new kids and partners that the spreadsheet is a total mess and people keep accidentally deleting rows while browsing on their phones. I need a better solution before the holiday shopping rush really hits next week.

My constraints are:

• must be free or super cheap
• needs a dead simple mobile interface for my tech-illiterate uncles
• has to allow people to mark items as claimed without the recipient seeing it
• supports a group of at least 25 people

What are you guys using that actually works for big groups? Im desperate...
