Im wanting to find a developer that can develop an app for me, but before I start shopping I have a very important question that needs to be addressed first. Is it possible to create an app where users can hit a button, and the application stores the amount of times the button has been hit. So if they hit the button 15 times it will show that they have hit the button 15 times? I know that is possible, but my real question is this. Take the same concept, but have multiple users hitting the button. So if I hit the button once and two other people hit it once, when I refresh the app it will show that the button has been hit 3 times. I want the app to be able to log everytime the button has been hit, and if 100 people are hitting the button at the exact same time can it keep up?
