Anyone using an app which shares recent stock levels of essential goods?

Is anyone actively using and sharing information about the replenishment of essential goods in their local groceries, Walmart, Coles (Australian region) etc

At the moment the delivery services in Australia in particular only cater to the elderly, self quarantined and those who should not go outside in public. For the rest of the general public, we have to rely on frequent travels to the grocery store hoping to see any restock in essentials such as milk, eggs, short life span items, toilet paper, pasta. Food which is not trackable to the general public. Does anyone have any suggestions on this? Happy to hear people's experiences and feedback across the globe.
