From the “how it works” blurb:

With the Pay What You Want bundles, you can get something incredible for as little as you want to pay while making the world a better place. And if you beat the average price, you’ll receive the fully upgraded bundle!

The current price required to receive all ten apps is $5.10. I’d pay that for Screens alone, but you get nine other apps alongside it for practically nothing.
