Button that counts clicks via a plugin?

I'm looking for a plugin that basically puts a button on my website and when people click that button there is a counter below it that is live.

To better explain it, i've attached an image showing an example.

On the image, you see a button that says "I'm Praying" and text below that says "600 people have committed to pray". The idea is if I clicked "I'm Praying", the number 600 would automatically change to 601.

Is there a plugin out there that does something this simple?
