Amazon is pulling out all the stops to entice you to use its Appstore for Android. True, Google Play is more convenient, but rarely does Google just give away $90 in premium apps and games as Amazon is doing right now. It's a good selection too with titles like Goat Simulator and Elements of Photography.
To grab all the freebies, you can head to Amazon's promotional landing page. It lists all 39 free apps and games, and most of it is solid (unlike most of Amazon free app of the day promos). Just add the ones you want to your Amazon account, and they can be installed immediately on the device of your choice via the Appstore client.
You don't have to rush to get the free apps right this moment, but this is a limited time offer. The promotion ends on August 15, 2015 at 11:59PM PDT.
