The unofficial "Facebook Lite Weed Apps" are actually or progressive web apps (PWAs) that create a custom interface for cannabis groups inside Facebook Lite.
Always check the developer name; official Facebook apps are developed by "Meta Platforms, Inc."
A built-in data tracker that shows: "This week, the app used 12MB. To order 3.5g of Wedding Cake, the app used 0.3MB." This is the killer feature for budget-conscious users.
