The Amazon free premium Android-y app of the day is DEAD. But it has a more user-friendly replacement. It is called the Amazon Underground. Hundreds of premium (normally for pay) Android apps are available for you to download and use for FREE. In-app purchases are free too. No ads. Amazon will pay the developers for use of the apps using the experimental scheme they launched with Kindle Unlimited earlier in the year. You must get the Underground version of the app, not the regular one. Amazon estimates a value of over $10,000 if you get them all.
Of those Underground apps, there are ten under Photography at the moment, including PhotoSuitePro 4, Perfectly Clear, pFolio, FlickFolio, etc. The Underground apps have a distinctive logo in their thumbnail as you can see below:
