Hey waps, We don't want to be those guys. This is why the quality of the design is as important as the content of the ad. We can show less ads to users than classic banners / interstitials, more elegant ads, and deliver high-quality content (apps, premium products).

(quick explanation, if an interstitial is being displayed every minute and has a 5% CTR, we can show one every 2 minutes because we have a CTR of 10%. So you can have twice as much -- or more -- ad-free experience time)
