Big Tech companies like Google and Amazon aren't the only ones invested in app-based literacy programs. Today, Kuato Studios unveiled a new learn-to-read app built around familiar Marvel stories. Marvel Hero Tales is an educational storytelling app meant to boost language and reading skills for kids ages seven to 11. It features Marvel-themed reading-based activities and superheroes like Spider-Man and Ms. Marvel -- plus new heroes every month. And it lets kids create their own characters and narratives.
