No. But as the app gains more and more users, the chances of no response for each beep will be lower and lower - down to almost zero. It can be zero because a beep can reach a radius of 1-5 miles of the location it's sent to, which is a 2-10 miles diameter. Certain locations will have millions of people within this range - and you're likely to find at least a few who can help you out. Also the price per beep is very low, at about $0.10 - $0.50 each, to reach millions of people.
