"There is actually a small collection of apps that scan the Play Store for free app deals. The most popular and effective include AppSales, PAGF, and App Hoarder.
These apps scan the Play Store for temporarily free apps and pass the savings on to you.
There exist a website, which does what the previous three apps do, but in website format."

There are a lot of good things about these apps. They all redirect to the Play Store. Thus, there are no third party downloads to worry about. In addition, they use actual, real deals in the Play Store so there is no piracy.
