I have just launched Testfly - an ultimate tool to help app makers hire thousands of verified app testers with just a few clicks.

Before Testfly, I've been running several tech communities over a couple of years and gathered 66,574 verified testers for this.

I put one of my apps on Testfly for a live demo so that anyone can see how it works - https://testfly.app/demo.

Of course, any positive/negative feedbacks are so welcome!
