Amazon has launched a new Android shopping app called Underground that provides access to free apps and games available via the Amazon Appstore. “Underground gathers and displays apps and games that are ‘actually free’ as Amazon calls it — with no hidden costs like in-app purchases,” reports The Verge. “But unless you are one of the hundreds of people still using the Fire Phone, it’s still a pain for most people to install any apps from the Amazon Appstore on an Android device.” To offer apps and games for free, Amazon has deals with developers to pay them on a per-minute played basis. Those interested in Underground can download the app from Amazon’s website.
