There is a website in China where you can download and install apps and games for free. I am not going to post the link as I am totally anti such practices.
What I cannot understand is people will spend up to £700 on a smartphone, but will not spend £0.69 on an app. Even £5 on an app is cheap. If you buy a coffee in Starbucks that will cost you £2.
Developers work really hard to produce these quality apps. Surely rewarding them will only encourage them to produce more apps, which in turn will add to your enjoyment.
