Would you use something like this?

If you had an office that caters to clients on a first-come-first-serve basis, would you use a queuing app to manage them?

That's the idea behind QueuePrime: to manage clients in a queue, and inform them when it's almost their turn without having to wait physically in the premises.

I don't have a landing page yet, against the norm here. Please roast the app. Thank you.
