New York -- Alicia Keys
, after giving birth to her son two years ago, said she wanted to create tools for children. Now she's launching an app for kids.
"The Journals of Mama Mae and LeeLee" is about a young New York City girl
's relationship with her wise grandmother. Keys produced music for the interactive app, which will be released Thursday for $3.99.
"It's a new adventure for me, and I'm really enjoying it," the Grammy Award winner said in an interview Wednesday.
The app is loosely based on Keys' relationship with her grandmother. It's centered in LeeLee's bedroom, and it allows users to read books, play music and write in a journal.
"It does remind me of my world," the New York-born singer said. "The piano, the journal, music's such a big part of my life, the city, all of that."
