This is a simple web site that I put together for small businesses that want to keep crowds small and avoid lines at their businesses while running at a limited capacity. It includes a simple app to keep tally which is then visible to people searching for you.
It's totally free for all to use and any feedback is appreciated!
why not just google the place and see it on the activity map? it shows you live traffic stats. it will be difficult to compete against google i imagine.
Google will give a relative measure of how busy the space currently is but doesn't give an exact number or a sense of how full a location is relative to any temporary capacity limits that might be in place.
