Google has quietly launched a Free App of the Week program in the Google Play store, giving Android users a little something to look forward to every seven days.

The first offering of the lot is Daniel Tiger Grr-ific Feelings, a $3 educational app from PBS with a set of games and activities for kids aged two to five. It’s buried in the Google Play’s Family section, and you’ll need to navigate there to get the offer or click here to get the app for free.

Google previously hasn’t had a mechanism to offer paid apps for free — once a developer lists their paid app as free, they can’t change it back and charge money for it again. The new deal uses an automatically applied discount code that brings the app’s cost down to zero.

It’s not yet clear how developers can opt into the program. We’ve contacted Google to find out more and will update this post when we hear back.
